Mixing & Mastering Engineers, Producers & Songwriters who worked with Matt Relevo

With a background in recording, performing, producing, composing, and arranging, EJ Rios brings an artist-first approach to creating polished, emotionally impactful mixes.

Classically trained in Tokyo, I've journeyed through jazz, rock, funk, pop and metal over the past 25 years. Keenly sensitive to emotions in music, combined with Perfect Pitch and pitch-colour Synesthesia, I bring color and sensibility to music. I work with musicians to give direction to their compositions and kick start their projects.

Hey, I'm Julz! I cut my teeth recording, engineering & mixing starting in 2010 when I began posting weekly covers to YouTube. In the meantime I'd provide BG vocals for artists like Ed Sheeran. Things evolved as I started to write and produce material to launch my own music, with some of the more notable sounds being Island-pop songs like "Gravity"

So, you need a song recorded for your demo and you didn't know who to hire and you have a minimum budget? I'm your guy! I've been singing and recording songs since I was 10 years old. I can sing in both English and Bahasa Indonesia.
