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).
In December 2010, Hammock released their fourth EP titled Longest Year, a beatless and wordless "mini-album" that was born out of the difficulty the band faced in 2010, including the near-total destruction of Byrd's home in the epic 2010 Nashville flood.
In 2005, Byrd joined The Choir and produced their album O How the Mighty Have Fallen. Prior to that, Steve Hindalong of the band had produced albums for Common Children, and co-written the worship song "God of Wonders" with Byrd. The Choir's 2010 album Burning Like the Midnight Sun includes the song "Legend of Old Man Byrd", which had originally been written for Marc and was performed at his 40th birthday party.
