Rich Costey is an American Grammy award-winning record producer, mixer, and engineer, whose work spans across hip-hop, rock, pop, indie, and electronica. At age sixteen, he became a DJ for a local radio station before going on to attend Berklee College of Music in Boston. While working at Q Division Studios as an assistant, he started collaborating with producer Jon Brion, whom he credits as an important influence. His first steady gig as a producer was with Boston indie band Swirlies. After college, Costey moved to New York City. In 1995 he became head engineer at Philip Glass' Looking Glass studio, and undertook projects at Michael Deming's Studio 45 in Connecticut. Costey then relocated to Los Angeles, where he engineered and mixed Fiona Apple's 1999 album 'When the Pawn...'. This attracted the attention of producer Rick Rubin, who hired Costey to mix records by Audioslave and Rage Against the Machine. In 2003, Muse recruited Costey to produce their breakthrough third LP, Absolution. His more recent credits include Foster the People, Birdy, Blink-182, Foo Fighters, Supergrass, Chris Cornell, Snow Patrol, Kasabian, Blondie, The Killers, Deftones, Sam Fender, Major Lazer, Pvris, Sigur Rós, Frank Turner, Chvrches, Santigold, Biffy Clyro, and Death Cab for Cutie.
