After several solo projects for Grunt Records, the members of Jefferson Airplane (including Paul Kantner, Grace Slick, Jorma Kaukonen, Jack Casady, Joey Covington and Papa John Creach) came together again in March 1972 for the first time in the studio since the "Bark" album was released in September 1971. Sessions at Wally Heider Studios continued for nearly three months, but tensions were high and several songs were recorded by each member recording their own part separately. David Crosby of Crosby, Stills, Nash and Young participated in the recording sessions, but Crosby's vocals were stripped from the record at the insistence of his label.
