Gus Seyffert was born and raised in Kansas City, MO. At a very young age he began studying music and started working professionally at the age of 14, playing dinner theaters and jazz gigs in KC. At 17, he moved to Los Angeles to study jazz bass at California Institute of the Arts with Charlie Haden. He left college after two years to continue working.

While living in Silver Lake, he transitioned into playing different styles of music and became a staple in LA’s East Side music scene, writing and playing around town with his band Willoughby, as well as Inara George, Mike Andrews, Charlie Wadhams, The Haden Triplets, and Benji Hughes, among many others. After meeting and working with some top tier touring and recording musicians and producers such as Greg Kurstin, Joey Waronker, Ariel Rechtshaid, Glyn Johns, and Nigel Godrich, Gus started touring and recording with acts such as Adele, Ryan Adams, Beck, The Bird And The Bee, The Black Keys, Norah Jones, Michael Kiwanuka, Roger Waters and Sia to name a few.

During these experiences, Gus had become obsessed with collecting all kinds of vintage instruments and recording equipment. This eventually led to a career as a music producer and engineer. He now owns and operates the recording studio Sargent Recorders in LA where he’s been spending the last few years developing bands, writing, and making records. Some production credits include Beck, Michael Kiwanuka, Bedouine, Dr. Dog, Jenny Lewis, James Supercave, Spain, Michelle Branch, Charlie Wadhams, and Willoughby.
