Jefferson Airplane, a rock band based in San Francisco, California, was one of the pioneering bands of psychedelic rock. The "classic" lineup of Jefferson Airplane, from October 1966 to February 1970, was Marty Balin (vocals), Paul Kantner (guitar, vocals), Grace Slick (vocals), Jorma Kaukonen (lead guitar, vocals), Jack Casady (bass), and Spencer Dryden (drums).
After 1972, Jefferson Airplane effectively split into two groups. Kaukonen and Casady moved on full time to their own band, Hot Tuna. Slick, Kantner, and the remaining members of Jefferson Airplane recruited new members and regrouped as Jefferson Starship in 1974, with Marty Balin eventually joining them.
