    Adam mastered our song Walking, and we were very satisfied with the end result. Good communication skills and a desire to make the recording as good as it can be. We got back a louder but still organic master, and we didn't feel the need to change anything.

    Amazing working with Adam. I work in the box so getting what I wanted from an out of the box master was a new experience for me but Adam knows his stuff and communicated well every step of the way. As far as the end product, I am very pleased with how my track stands next to commercial tracks and the warmth from the hardware Adam uses gives my music the intimate and mature sound I was looking for.

    I had an album that needed some personal attention and attention to detail, in that it was full of layered guitars with different textures, gritty drums, prominent bass, as well as a little noisy with loosely edited mix tracks. Adam was able to see the process through and get the drums knocking, bass bumping, and every element shining, yet also retain their grit, wear, and character. He was easy to communicate with, and I'm pleased with the end result and process. Thanks again, Adam.

    Adam is a true professional who honestly cares about each job he does. The song he mastered, had been previously mastered by others which I was unhappy with. I'm glad I found Adam, or I still would be looking for that perfect master. He took my mix and made it come to life... a hard song to master as there are many dynamic builds and bursts. He mastered it to perfection while ensuring to retain the songs identifying dynamics.
    Completed before the deadline. Gave great advise.
    Thank you Adam!!!

    No cap, we thought our track was good, but Adam took it to A WHOLE NEW LEVEL. Super-professional, knowledgable and helpful every step of the way. Took the time to provide us detailed feedback on the mix (at no extra cost) before we even got started. Adam comes across as a guy who genuinely wants to work with you and see you win and we couldn't be happier with the final product. The world could use more mastering engineers like him. 5 stars for sure!

    Mount has been extremely professional, patient, and true to his word. He has delivered a Stellar Master ahead of the expected turn around time. Mount was able to quickly, kindly, and accurately make revisions to the track, making this experience enjoyable and efficient. After my experience with Mount I highly recommend using his outboard mastering skills & ears to anyone looking for a true professional to seal the deal on a mix.

    You do not need to look any further, this is your guy. Adam is the most knowledgeable passionate sound engineer that you can find. He takes time to listen to your track and become part of your work. Most sound engineers will barely listen to your music, or they toss your song into an algorithm. Adam makes sure he truly polishes your track and that is just something you cannot replace. He is also very professional and pleasant to work with or talk shop with. Highly recommend.

    I write this review with hesitation because if everyone knew the mastering process could be this great then there'd be no time for me!

    In all seriousness though, ive worked with quite a few mastering engineers and adam has a different approach. Hes a real musician who brings his musicality to his work and really internalizes the material and makes your ideas better (not just louder). My favorite part of working with Adam is the way he's able to give a piece of music just what it needs and not overdo it. I highly recommend him and look forward to working together on more projects.

    I've had nothing but incredible experiences working with Adam at Mount Olympia, for my own projects and for projects I've produced for other artists. Sometimes I think "this sounds so good, mastering won't make a big difference" but with Adam, I've always found a big improvement. And when I sent him a project I'd never been 100% happy with, I could really appreciate and enjoy it for the first time when I heard the masters. He provides that extra bump that makes my music ready to sit next to, or above, anything else out there. Having that confidence is priceless!

Interview with Mount Olympia Mastering

  1. Q: Tell us about your studio setup.

  2. A: Mount Olympia is run out of a world-class, Platinum-Award winning mastering house, located in the Arts District of Downtown LA. I work on PMC monitors, alongside mastering veteran Mike Bell (Diplo, Glitch Mob, Flostrodamus) in a tuned environment, sharing a common workflow on our combined compliment of outboard mastering equipment.

  3. Q: What was your career path? How long have you been doing this?

  4. A: Prior to specializing in mastering, I had worked in nearly every aspect of contemporary music (staff producer, mix engineer, production manager of Hollywood nightclubs and venues, songwriter, musician, and educator). I was fortunate to study music and music technology at a college with a strong emphasis on acoustics & electroacoustic synthesis (and occasional lab visits from Dr. Bob Moog himself!) Then I headed to NYC, and cut my teeth as a mix and recording engineer at studios like Big Blue Meenie and Manhattan Center Studios. During this time I was the staff mixing assistant on productions for Kanye West (Bigger, Faster, Stronger), The Scissor Sisters (their multi-platinum "Ta-Dah" LP), Moby, Daddy Yankee, and Alice Smith, among many others, as the right hand man and co-pilot to top producers and engineers like Dan Grech-Marguerat (Radiohead, Beck, Lana Del Rey) and Jimmy Douglas (Justin Timberlake, Timbaland). My transition into mastering happened organically and gradually. After many years freelancing in Los Angeles, I was tapped as a professor of mixing at a highly regarded music production school. I realized that times were changing when I found myself in a classroom giving away all my hard-earned mixing secrets! It became clear that my would-be clients were all becoming legitimate mix engineers as a result of teaching my methodologies. Having earned their trust, former mix clients and students quickly began requesting my services for mastering. In time, I had amassed a following as a mastering engineer, acquired the gear, and developed important relationships with other highly-regarded mastering engineers in LA. Within a few years of building my chops and experience, I was sharing a beautifully built-out mastering studio with Diplo's mastering engineer, Mike Bell, in DTLA.

  5. Q: Tell us about a project you worked on you are especially proud of and why. What was your role?

  35. Q: What's your strongest skill?

  36. A: coming soon!

  37. Q: What do you bring to a song?

  38. A: coming soon!

  39. Q: What's your typical work process?

  40. A: coming soon!

  43. Q: Describe the most common type of work you do for your clients.

  44. A: I do a ton of mastering for indie artists and smaller labels. They run the gamut from the heavy, loud, & subversive electronic stuff to the downtempo, ambient, & the rustic ones.
