Carey Marcus "Marc" Byrd is an American musician, writer, and producer best known as one-half of the post-rock/ambient duo Hammock, along with former Common Children band-mate Andrew Thompson.
Since its formation in 2005, Hammock has released six full-length albums and five EPs. One review of Hammock's most recent record Oblivion Hymns remarked that Hammock "...has gone on to become one of the foremost purveyors of affecting ambient post-rock on the scene." Byrd was also involved in the 2006 ambient art project The Sleepover Series, Volume 1, which featured five solo tracks written and performed by Byrd.
After an impromptu invitation to give their first-ever live performance as Hammock at the overseas debut art exhibition of Riceboy Sleeps, the artistic collaboration between Jón Þór (Jónsi) Birgisson (lead singer and guitarist of Sigur Rós) and Alex Somers (graphic designer and member of the band Parachutes), Marc and Andrew wrote brand-new songs to celebrate the occasion, an undertaking which evolved into their album, Maybe They Will Sing for Us Tomorrow (Darla Records).
