Following the commercially unsuccessful "Baron von Tollbooth & the Chrome Nun" (1973; credited to Kantner, Slick and Freiberg) and "Manhole" (1974; credited to Slick), Jefferson Airplane evolved into Jefferson Starship in January 1974. The initial lineup consisted of the remaining members of Jefferson Airplane (Kantner, Slick, Freiberg, Barbata, Creach); bassist Peter Kaukonen (soon replaced by British multi-instrumentalist Pete Sears, a veteran of Creach's debut solo album and "Manhole"); and lead guitarist Craig Chaquico, a member of Grunt Records band Jack Traylor and Steelwind who contributed to the Kantner/Slick solo albums beginning with "Sunfighter". They appropriated the name from Kantner's "Blows Against the Empire", with Bill Thompson convincing the group that maintaining the connection was prudent from a business standpoint. Reflecting the transition, the album "Dragon Fly", released in September 1974, was credited to Slick, Kantner and Jefferson Starship.
