Jefferson Airplane

Jefferson Airplane was the first of the San Francisco psychedelic rock groups of the 1960s to achieve national recognition. Although the Grateful Dead ultimately proved more long-lived and popular, Jefferson Airplane defined the San Francisco sound in the 1960s, with the acid rock guitar playing of Jorma Kaukonen and the soaring twin vocals of Grace Slick and Marty Balin, scoring hit singles and looking out from the covers of national magazines.
