OK Go

OK Go is an American rock band formed in 1998 and based in Los Angeles, California. The band is composed of Damian Kulash (lead vocals, guitar), Tim Nordwind (bass, vocals), Dan Konopka (drums and percussion), and Andy Ross (guitar, keyboards and vocals).

The band is known for its quirky, complex music videos which are often elaborately choreographed to be filmed in a single long take and make extensive use of practical effects and optical illusions.

The band was formed in Chicago, Illinois, moved to Los Angeles in 2001, released two studio albums before original guitarist Andy Duncan left in 2005, and has released three more since. The band's video for "Here It Goes Again", in which the band dances on moving treadmills, won the Grammy Award for Best Music Video in 2007.
