Hot Tuna began during a break in Jefferson Airplane's touring schedule in early 1969 while Grace Slick recovered from throat node surgery that left her unable to perform. Kaukonen, Casady, Kantner and drummer Joey Covington played several shows around San Francisco, including the Airplane's original club, The Matrix, before Jefferson Airplane resumed performing. Their early repertoire derived mainly from Airplane material that Kaukonen (the band's frontman) sang and covers of American country blues artists such as Reverend Gary Davis, Jelly Roll Morton, Bo Carter and Blind Blake. In addition, Casady and Kaukonen played as a duo under the moniker with Kaukonen on acoustic guitar and Casady on electric bass. From October 1969 to November 1970, Hot Tuna (also including Balin and, following Kantner's departure, a dedicated rhythm guitarist in their electric performances until November 1970) performed as the opening act to Jefferson Airplane with a combination of both electric and acoustic sets.
