Hammock is an American ambient post-rock duo formed in Nashville, Tennessee, in 2005 by Marc Byrd and Andrew Thompson.

[5] Hammock was formed in Nashville, Tennessee, by Marc Byrd and Andrew Thompson, both former members of the alternative rock band Common Children.

"[9] In March 2005, music written and recorded from these initial sessions over a two-and-a-half year period was released on Hammock's debut album, Kenotic.

[10] Hammock's debut live performance was at Chuck Dodson's Gallery@404B in Hot Springs, Arkansas, on August 3, 2007, at the after-party of an event to honor the Icelandic artistic duo Jónsi & Alex.

The group wanted a change in musical direction as they developed a new fanbase with the previous album, so they incorporated orchestral arrangements and fuller instrumentation on their new material.

[15] That December, Hammock released their fourth EP, 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 2010 Tennessee floods.

[16] On March 8, 2011, the band issued a cover of Catherine Wheel's "Black Metallic" as a digital single, featuring vocals by Byrd's wife, Christine Glass (the couple had previously collaborated as a duo, GlassByrd).

On October 5, 2011, they released a four-song collaboration EP with Steve Kilbey and Tim Powles of the Church called Asleep in the Downlights.

The album was released on November 26, 2013, and was a notable departure from their previously guitar-focused sound, adding a neoclassical element with a full orchestra, children's choir, and vocals from Timothy Showalter (Strand of Oaks).

[20] Haydon Spenceley, reviewing for Drowned in Sound, stated that the album has "clarity, purpose, drivenness, even, not words that would necessarily be associated with this stellar band's earlier work...

Hammock collaborated with Matthew Perryman Jones in 2013 on the song "Unknown", released as part of the Nashville Indie Spotlight 2014 compilation album.
