Born from a friendship nurtured during their days at the University of California Santa Barbara, the band consists of Zach Gill (Keyboards/Vocals), Steve Adams (Bass Guitar/Vocals), Dan Lebowitz (Guitars/Percussion/Vocals) and David Brogan (Drums/Vocals).

Originally a nine-piece band featuring a brass section called The Animal Liberation Orchestra and the Free Range Horns, the band began drawing enormous attention in the Santa Barbara area with their rousing stage shows. When Zach, Dan and Steve returned to their hometown San Francisco, they stripped back down to a quartet, playing with a wide variety of different drummers. Finally, in 2002, the trio reunited with drummer David Brogan (with whom they had previously played in college) and the ultimate version of Animal Liberation Orchestra was solidified.
