Tesla is an American rock band formed in Sacramento, California, in 1981. Known for their bluesy, acoustic-based hard rock style, they stood out among the glam metal bands of the 1980s with their more earthy, authentic sound. Their most notable work includes the 1989 album "The Great Radio Controversy", which produced the hit power ballad, "Love Song." Despite multiple lineup changes, lead vocalist Jeff Keith and guitarist Frank Hannon have remained consistent members, contributing significantly to Tesla's enduring presence in rock music.
