I'm Gus Elg, the mastering engineer and owner of Sky Onion Mastering. Since 2002 I've been helping a wide variety of musicians make records. I've been involved in rock, electronic, folk, jazz, orchestral, hip-hop and world music projects from all over the globe. As a music lover I sincerely enjoy hearing whatever new mixes are waiting in my inbox every day. When I'm not mastering records I can be found geeking out over audio electronics, walking my dog Bernie around the neighborhood, camping, getting outdoors, and playing music of my own.

I grew up in Spokane, WA, graduated from Washington State University in 2001, and moved to Portland to pursue playing in bands and audio engineering. After gaining considerable experience mixing and recording I eventually tried my hand at mastering. I soon realized that was where my place was in the music business, so I dedicated Sky Onion exclusively to mastering in 2008 and it became my full-time job in 2012.
