Matt literally saved this project. I was on mix 30 with the engineer I was using and Matt took what we had and hit it waaaaay out of the park in just 2 mixes and 2 days.

Matt delivered me his mix with few revisions and every single time did exactly what I wanted and at amazing speed!

Matt's mixes are inspiring!! he is a rare combination of talent, work ethic, and personality. His ATMOS mixing knowledge is unrivaled and he has taught me a lot. every interaction i have had with him has been either super pro or laughing with each other.
Super talented and easy to work with!

I've worked with Matt in the past on multiple songs, and they won't be the last. I forget how my first contact started with him, but I do remember the feeling. From the short, but direct conversation we had, I was left feeling very confident and at ease that the songs I put so much time into would also be treated the same as they were being mixed. The outcome, every time is more than I hoped!!
