Broken Bells

Broken Bells is an American indie rock band composed of artist-producer Brian Burton (better known as Danger Mouse) and James Mercer, the lead vocalist and guitarist for the indie rock band The Shins. Broken Bells compose and create as a duo, but are joined by a full band on tour. The live band included Conor Oberst and the Mystic Valley Band sidemen Nate Walcott and Nik Freitas, and Jonathan Hischke and Dan Elkan, both ex-members of Hella. Following the success of their first self-titled album, Broken Bells, Mercer and Burton announced intentions to record a follow-up, and released a new EP, Meyrin Fields, on March 29, 2011.
