After the acrimonious events that resulted in Jefferson Starship's 1984 evolution into Starship, Kantner reunited with Balin (who joined Jefferson Starship in January 1975 following a guest appearance on "Dragon Fly" before leaving once more in 1978) and Jack Casady in 1985 to form the KBC Band. They released their only album, "KBC Band", in 1987 on Arista Records. On March 4, 1988, Grace Slick made a cameo appearance during a Hot Tuna San Francisco performance at the Fillmore (with Kantner and Creach joining in), facilitating a potential reunion of Jefferson Airplane.
