Jefferson Starship is an American rock band from San Francisco, California that evolved out of the group Jefferson Airplane following the departure of bassist Jack Casady and guitarist Jorma Kaukonen. The band went through several major changes in personnel and genres through the years while retaining the same Jefferson Starship name. The band name was retired in 1985, but it was picked up again in the early 1990s by a revival of the group led by Paul Kantner.
