Jefferson Airplane

One of the quintessential San Francisco psychedelic bands, the Jefferson Airplane brought together interests in acoustic blues, folk, and rock music. Add political topicality and modal improvisations, and you have an inspired, mind-bending sound that could have only sprung forth from the late '60s. In their initial, most beloved phase, they were powered by the powerful dual lead vocals of Grace Slick and Marty Balin and the serpentine guitar of Jorma Kaukonen. They went through a traumatic series of personnel and name changes over the decades (they ventured into commercial AOR in the late '70s and early '80s) but their early work retains its seminal power.
