Loose Fur is an American rock band comprising of Wilco members Jeff Tweedy and Glenn Kotche, and Wilco collaborator Jim O'Rourke. The trio first convened in May 2000 in preparation for a Tweedy performance at a festival in Chicago. Tweedy was offered the opportunity to collaborate with an artist of his choosing, and he decided to work with O'Rourke. O'Rourke brought Kotche to a rehearsal session, and the trio recorded an album's worth of songs. The trio have since released two albums, 2003's Loose Fur and 2006's Born Again in the USA, for Drag City Records. The band is a side project of Wilco, and only toured once.
The band is noted for its influence on Wilco's fourth album, Yankee Hotel Foxtrot. Tweedy was unhappy with how music from the initial recording sessions for the album were sounding, resulting in a lineup change for the band. Both O'Rourke and Kotche replaced members of Wilco during the recording sessions for the album, and are still contributors to the band as of 2007.
