Burgers, Hot Tuna's third album, marked a crucial transition for the group. Until now, Hot Tuna had been viewed as a busman's holiday for Jefferson Airplane lead guitarist Jorma Kaukonen and bassistJack Casady. Their first album was an acoustic set of folk-blues standards recorded in a coffeehouse, their second an electric version of the same that added violinist Papa John Creach (who also joined the Airplane) and drummer Sammy Piazza. Then the Airplane launched Grunt, its own vanity label, which encouraged all bandmembers to increase their participation in side projects. Burgers, originally released as the fourth Grunt album, sounded more like a full-fledged work than a satellite effort. It was Hot Tuna's first studio album, and Kaukonen wrote the bulk of the material, not all of it in the folk-blues style that had been the group's métier.
