There is much to love about the music of the โ90s โ bands like Radiohead, Rancid, Blink-182, Bjork, Nirvana, The Bouncing Souls, PJ Harvey, Portishead, Nine Inch Nails, Dropkick Murphys, Sunny Day Real Estate, Sublime, Tori Amos, G. Love & Special Sauceโฆ all those songs and sounds of my formative years. Making mixtapes was my generationโs way of sharing feelings, of capturing memories and crystalizing them on a cassette tape for eternity (or at least until the tape melted on your dashboard). It wasnโt a โplaylistโ like today, where you can randomize the song order. A mixtape is a carefully curated selection of songs laid out in a meaningful order. Itโs an analog artform that drowned in the rising flood of digital media.
The magic of the mixtape is revived in Netflixโs aptly named filmed Mixtape โ a charming tale of a young orphan girl named Beverly who finds her momโs mixtape in a box in the basement, but before Beverly can play it through the tape is destroyed in her walkman. Beverly sets out on a quest to track down each song on the tape, to learn about who her parents were, and to find out who she is along the way. Itโs a heartwarming film with a cool punk-driven soundtrack.
Here, Formosa Groupโs Emmy and MPSE Award-winning supervising sound editor Odin Benitez and I chat about the lasting impact of the 90s, musical influence and evolution, the challenges for him and his sound team on Mixtape, mixing remotely, and more!

Mixtape is such a fun, heart-warming film. I loved the โ90s Alt-Rock tracks and punk tracksโฆ

Odin Benitez (OB): Itโs interesting that these โretroโ films are during a time when I was already a professional. It makes you feel old.
But itโs cool. Valerie wanted to make sure that the period of the film was established. At every opportune time, we would have a radio announcer mention Y2K and that whole worry, or relevant commercials from that period, and music that reflected the time.
ย
When you look at the cars and clothes in the film, there isnโt a striking difference between then and now. Today, you still see people driving around in cars from the โ90s, and wearing jeans and tee-shirts. The 90s are still alive and presentโฆ
OB: I heard a statistic that Nirvana is actually the halfway point between now and the beginning of Rock โnโ Roll.
Thatโs hard to believe that there had been so much innovation from the โ50s to the โ60s to the โ70s and up to the โ90s, but then after that, the innovation doesnโt seem to be there anymore, or maybe not as noticeable. Itโs just a different beast, I guess.
ย

Yeah, an Alt-Rock band today sounds very similar to one from the Nirvana era. Thereโs not much radical difference. You have synths, guitars, and distortionโฆ
OB: Yeah, take Bruno Mars, for example. Heโs basically harkening back to Prince and the Minneapolis sound at times, which was a total innovation in its time.
Itโs interesting. I wonder if itโs because of the decentralized nature of the music industry, how people are basically going through and finding their own likes and dislikes, finding their own audiences. Itโs not so directed by one music industry. Although, thatโs still going on with certain artists.
Do you know that song โBrutalโ by Olivia Rodrigo? Well, thatโs basically โPump It Upโ from Elvis Costello. I played that song for my girlfriendโs daughters who really like her music and they were surprised. But then again, Elvis got it from Bob Dylanโs โSubterranean Homesick Bluesโ and he got it from Chuck Berryโs โToo Much Monkey Business.โ So, the influences all carry forward.
ย

Itโs influence but interpretation, too. The artist puts their unique spin on itโฆ
OB: Thatโs how most musical artists work. They are influenced by other artists around them. I think that Paul McCartney said The Beatles were plagiarists extraordinaire. And my son Sean, too, writes songs and heโll get inspired by an artist โ whether itโs Harry Styles or Arctic Monkeys or whoever โ and then he starts writing.
ย

Itโs interesting, too, to hear the progression of a band that has a long career because their influences change over the years, and they have an evolution as a band within this wider context of music evolving as a whole. Look at Radiohead, from Pablo Honey to A Moon Shaped Pool thereโs such a changeโฆ
OB: OK Computer is an amazing album.
Radiohead is interesting, too. Their song โCreepโ is basically the Holliesโ โThe Air That I Breathe.โ
I think Brian Eno said the guitar in every artistโs hand becomes kind of a unique instrument. There are things that Jimi Hendrix can do that I donโt think anyone can duplicate. Keith Richards, too. Thereโs just this sound that they have and itโs unique.
ย

Music obviously plays a huge role in Mixtape. In what other ways did director Valerie Weiss want to use sound to help tell this story?
OB: We touched on it a bit earlier but Iโd say that Valerie wanted to feel as if youโre in the โ90s era, and also in that location of Spokane, Washington. She wanted to be true to the era and the area.
She wanted to be true to the era and the area.
We had lots of commercials on the radio and in the record store. She wanted to make sure we had a lot of music from the era that went into this sonic production design. That was a big area.
One of the biggest challenges for sound in the film was in the forest, where the kids go to that haunted forest. They wanted to create this spooky, ghost-like ambience but when you watch the film, there isnโt anything visually spooky about it. So our job was to figure out how to get the sound they want that worked with the visuals they have, without it coming across as corny or unrealistic.
We went through a lot of iterations. Russell Topal was my sound effect editor/sound designer. He did a great job on the film.
โฆwe ended up working with subtle winds and we also did movement in the forest, like branches falling or snapping and wood creaks.
Sometimes we had a lot of birds and animals in the forest, but they asked us to pull back on that. Valerie at one point suggested a woodpecker, which I thought was a great idea. But then they decided to not use that.
Instead, we ended up working with subtle winds and we also did movement in the forest, like branches falling or snapping and wood creaks. We were trying to make the forest come alive with those sound effects. That seemed to be effective enough, along with the subtle winds. We also brought in some birds and animals to punctuate certain moments.
But that was definitely one location that we kept going back to and kept evolving until we got it to its final form.
โฆsheโll have a boombox playing music that should inspire the scene.
One interesting thing that Valerie does when she shoots is that in certain scenes sheโll have a boombox playing music that should inspire the scene. Obviously, thatโs going to create an issue with dialogue and in some cases, we needed to completely loop scenes or sections where the music bleed was too extensive and we couldnโt get rid of it.
For instance, there was one scene where they were singing that song โTeacherโs Petโ โ it was part of that sequence where they were creating the school mascot buttons. It cuts between that to scenes in the garage where the girls are playing along to the song. In that case, they had tons of music bleed and I think only one boom microphone was working. So Harrison Meyle (dialogue/ADR supervisor) had to loop all that and the kids had to redo the vocals of that song on the ADR stage.
We were going to reproduce their instruments too โ the drums and the guitars.
We were going to reproduce their instruments too โ the drums and the guitars. We were going to do it in a garage-style format. But, in the end, itโs the original stem of the music from the song with the kidsโ ADR singing. Thatโs what made it into the final movie.
There were several instances like that, where we needed to completely loop them. The end song was also one of those moments as well.
Another challenge was that we had to come up with some interesting button-making sounds that cut through that song. The foley team really came through for that. And we heightened it with some sound effects.
The filmmakers also wanted to make sure the fireworks felt rightโฆ
The filmmakers also wanted to make sure the fireworks felt right, that they werenโt too big at the beginning because they wanted them to build at the end. So we needed to find a careful balance that would mix with the song but wouldnโt be too strong at first. The fireworks we had initially were way too big for them, but we found a good middle ground for the final, and I think it works well.
In terms of the overall soundtrack, some of the filmmakers wanted to go more minimalistic and others wanted the space filled with environmental sounds and off-stage mini-dramas. So, we went back and forth with adding off-screen car-bys and then taking them out, adding in birds and then taking them out. There were some conflicts among the filmmakers as to how much of the world we should hear. I remember us adding in more and more sound even though there was already a ton of stuff there because it was something that kept coming up.
I think sometimes when we add too many off-screen sound effects on certain films, itโs because the director isnโt confident that the scene looks real.
I think sometimes when we add too many off-screen sound effects on certain films, itโs because the director isnโt confident that the scene looks real. Theyโre worried that it looks like a set because they know itโs a set. Not to say thatโs what was happening with this film, but itโs usually a tell-tale sign when they want to have a lot of sound happening off-screen that theyโre not confident in their location.
In the end, the filmmakers on Mixtape were very confident in the drama and the scenes they were portraying. I think it was the right decision to just let the scene play and to not have distracting car-bys and too many off-screen birds.
In some of the scenes, like the record shop, we did use off-screen sound to make it feel like there was a lot of town life happening around them. Sometimes we played that up and other times we let the drama take the scene. But when you look out the window of the record shop, you donโt see a lot happening. So our challenge was figuring out how to make it sound like there was a vibrant town outside without making it feel out of place with the visuals.
Another location that Valerie wanted to focus on was the club. She really wanted that to feel real.
ย

Looking at that club scene โ where the girls and their record shop โfriendโ go to see the Wes Kelly Band โ how did you handle the music and sound of that scene?
OB: That was hard for me because I donโt have many great tracks for nightclubs. Itโs hard to record one, too, because theyโre usually playing music at the club. And the club in the film wasnโt a giant auditorium full of people. Itโs more like a bar, which also typically has music.
Loop group played a huge role in helping to bring out the detail.
Another factor is that the club had two different areas: close to the stage and the bar area. The filmmakers wanted to hear the difference between those two. I was able to find a few tracks that helped with the body movement of the people near the stage (like dance footsteps) to help you feel the presence of the people there, and for the bar, we had clinks and bartender routines.
Loop group played a huge role in helping to bring out the detail.
I once did a low-budget film where they didnโt book any loop group and we thought we could cover it with effects. But once we got on the stage, we realized how much we needed group. There are different layers that work together to create a crowd sound. You have an ambience bed walla to fill the space, the loop group that helps to lift it off the screen, and then the principle dialogue. Missing that group layer is quite noticeable. The group layer for the club scene also helped to add responses from the audience.
During the mix, our re-recording mixers Andy DโAddario and Emilie Corpuz did such a phenomenal job recreating that feel that youโre in a nightclub. That was one of the biggest challenges they had because they were doing most of the film previews via Zoom or PIX, and they were recording the audienceโs responses as well so that brought the overall bandwidth of the showโs audio really low. So as they were previewing the film, the audience was hearing awful audio quality. There was really nothing we could do no matter how good we got the tracks to sound. Once it was put through that pipeline it wasnโt going to sound good. Iโll be glad when we can have screenings in real theaters again!
So as they were previewing the film, the audience was hearing awful audio quality. There was really nothing we could do no matter how good we got the tracks to sound.
So once we got to the dub stage, they were very keen on making it sound nice and full, and we achieved that. The filmmakers were very happy. And of course, it sounds great on Netflix.
As for the music, the Wes Kelly Band wasnโt doing anything live. It was all playback. That was one of the big mix challenges for Andy [DโAddario], to make that sound like youโre in a club. There were different perspectives, too. Sometimes the camera was close-up on the singer and sometimes youโre in the crowd in front of the stage and then youโre further back in the bar. Andy had to work really hard to make that work.
The second song they played at the club, the more ballad-type song, already had a really nice treatment on it so it wasnโt quite as challenging.
ย

For the girlsโ concert at the end, Iโm sure that was all playback. I donโt think it would be possible for the kids to get that good at playing instruments that quicklyโฆ
OB: Yeah, thatโs one of those conceits, right? Any musician knows that theyโd have to struggle hard even to just play a chord let alone a whole number. When Anti, the record shop guy, goes up to play itโs more believable because he was supposedly in a band.
But I do think the actress who played Beverly (Gemma Brooke Allen) was singing the vocals.

What would you want other sound pros to know about your work on Mixtape?
OB: The biggest thing about this film โ and itโs the first time I ever had this challenge โ was that I couldnโt be on the stage for the mix. I had gotten back from Mexico and due to Covid protocols, I wasnโt allowed back on the stage. Todd Toon was an additional supervising sound editor on the film and was on the stage when I couldnโt be there. So I had to monitor the mix via ClearView. Also, I think Harrison had to do the same thing because we couldnโt have too many people on the stage.
I was surprised at how well I was able to hear what was happening with the mixโฆ
The ClearView approach worked great. We were able to handle any effects requests quickly by uploading the edited files they needed. I was able to listen to the dub as well. It was a stereo feed but when you think about this film being a Netflix release, you know the audience is going to be listening back in a near-field environment. I was surprised at how well I was able to hear what was happening with the mix, and I was able to ask the mixers to raise this or lower that. It was a surprisingly effective way of dealing with that situation where you canโt be on stage.
Almost every other film Iโve worked on during the pandemic, Iโve been on the dubbing stage. This film was the exception, but it did work out.
ย

Attending the mix remotely and getting to experience that as how a producer or even director might experience it, did that give you confidence in this remote mixing process?
OB: Yeah, I think so. I do have a set of really good headphones though. Oftentimes, I donโt know what the producers are monitoring through. Are they listening through their Mac speakers? Iโve stressed to post supervisors that it would be great if we all had the same headphones so that we had a common ground for playback. This way weโre giving notes on the same playback of the mix. Iโve done films where the filmmakers say that the sub sounds tinny. And I ask, โWhat are you listening through? It sounds huge to me.โ Then when they hear it on a stage, theyโre like, โOh, yeah, that sounds huge.โ
So, it does work but I hope we donโt have to do it much longer.
If everyone is monitoring on the same headphones, then at least we have a common ground and we can give notes properly.
So, it does work. Youโre not hearing things in Atmos or 7.1, so thereโs a drawback there. But at least youโre getting specific details like the lines of dialogue, and key sound effects, and you can hear if the music is playing correctly.
I had done a mix where the Apple executives were listening on their Apple headphones and theyโd have good notes โ like, the music was too loud here or we could be more adventurous there. So, it does work but I hope we donโt have to do it much longer.
