The Problem

You, an impassioned musician, poured your heart and soul into meticulously crafting a beautiful song, investing countless hours in every chord and lyric. Yet, despite your undeniable talent in composing music, a persistent problem remained. The final mix of your song lacked the professional polish necessary to make it stand out. You’re aware of the importance of high-quality mixing and mastering in achieving that radio-ready sound that connects with a broader audience but lack the technical expertise needed to accomplish this crucial step.

Matty is my go-to mixing and mastering engineer. I have been working with him for several years and he has essentially become an extension of me and my creative team. The quality of his work is the result of the intention and focus he puts into every project. My trust in his sonic choices goes so deep that I defer most (if not all) of the post-production mixing and mastering decisions to him. I'll get something back and if there are changes needed, it's usually of the personal preference variety. The overall quality of his work never misses. He never disappoints. If you have a project on a scale of 1-10, with 10 being the best, sitting at say a 6 - I can guarantee, Matty is the guy who can take it to 20.

I'm Portuguese so my album was composed and written in Portuguese. I was expecting some issues regarding that. But Matty dealt with it like if he was working with English written material. Amazing sound! The orchestration was complex but I can hear every single detail on each song. Amazing mixing, better mastering! And Matty is a fantastic guy with a lot of patient to endure all my requests!!! I can't recommend enough!!!

Matty is fantastic. We've been working together for years and he's professional, timely, and talented. His mixes always sound crisp and I've gotten positive feedback from plenty of unbiased sources. Also his pricing is very fair. My standards are high but I would 100% recommend him to others.

I have never before worked with a more professional studio engineer than Matty! Matty is a perfectionist that delivers his mixes at the highest quality level. Even though he has worked with some of the most successful artists in the world, he treats every client the same way. He treated us very nice and respectful from the get-go and we could tell that he wasn’t going to be satisfied until we were. We have booked Matty several times and he delivers the same high level every time. And that he is using high quality equipment is a big plus. We would highly recommend Matty Harris as your studio engineer anytime.
