Begun as an acoustic spin-off of the Jefferson Airplane, Hot Tuna eventually became the full-time focus of founding members Jack Casady and Jorma Kaukonen, emerging as a popular touring act of the 1970s. The two were lifelong friends, growing up together in Washington, D.C., and playing in the group the Triumphs. After high school, guitarist Kaukonen and his government-service parents relocated to the Philippines, but he returned to the U.S. in time for the advent of psychedelia, landing in San Francisco and co-founding the Airplane in 1965.
