Tesla is an American rock band formed in Sacramento, California in late 1981 by bassist Brian Wheat and guitarist Frank Hannon as Earthshaker, and later City Kidd. Lead vocalist Jeff Keith, drummer Troy Luccketta, and guitarist Tommy Skeoch joined them by 1984. By 1986, the band had changed from its glam-derived sound to a 'rootsier' direction under a new name: Tesla. In 1996, the band disbanded, with members devoting themselves to solo projects. In 2000, they reformed, but Tommy Skeoch departed the band in 2006 and was replaced by Dave Rude. They have sold 14 million albums in the United States.
