Kaukonen and Casady moved on full time to their own band, Hot Tuna. After 1972, Jefferson Airplane effectively split into two groups. Two songs from that album, “Somebody to Love” and “White Rabbit”, are among Rolling Stone’s “500 Greatest Songs of All Time.” 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). Their 1967 break-out album Surrealistic Pillow ranks on the short list of the most significant recordings of the “Summer of Love”. They were headliners at the three most famous American rock festivals of the 1960s-Monterey (1967), Woodstock (1969) and Altamont (1969)-and the first Isle of Wight Festival (1968) in England. Formed in 1965, the group defined the San Francisco Sound and was the first from the Bay Area to achieve international commercial success. Jefferson Airplane, a rock band based in San Francisco, California, was one of the pioneering bands of psychedelic rock.
