    Thank you Matis for offering this service of yours. He's quick to respond to his clients and he gets the job done efficiently. I've only asked him to do simple audio work, but he gets it done. He's also a very honest and polite guy. I definitely recommend his services!

    by Sashi Papi

    This guy has been doing my mix and mastering for 2 years.
    Every one of my songs has been done by him I definitely recommend him after all he only gets better and better. In the first place I’m surprised he didn’t start expending his business earlier. He’s definitely worth it you should give him a try!

Interview with O'leaf

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

  2. A: Generally, you'll see me recording, mixing, and mastering. The artists I work with know they're getting the whole package when dealing with me, pause. At times, a special request occurs for a custom beat, I'm here for the job. You'll rarely see another engineer as invested as I am—clients are family.
