Jefferson Airplane with vocalist Grace Slick
The band got their first gig in San Francisco in 1965, and vocalist Grace Slick joined them in '66. They went on to the Fillmore, the Berkeley Folk Festival, the Monterey Jazz and Pop Festivals, and Woodstock.
This band, with psychedelic backdrop and album covers, openly described the drug culture. Grace Slick closes White Rabbit (a reference to Alice in Wonderland), with the infamous exhortation to the hip kids of the sixties.
"Feed your head" means partake of the mind-altering drugs of the time; take a "trip" on LSD or speed or magic mushrooms.
Another hit was Somebody to Love. In 1968, the band made the cover of Life magazine. In 1996 Jefferson Airplane made the Rock and Roll Hall of Fame. In this 2008 video interview, Grace looks back.
