Ah, this may part of the answer... from wiki
As the album was being recorded, Paul Kantner became frustrated with the album's direction. Before the sessions came to a close, he stole the master tapes, put them in his car and drove around San Francisco for a few days and wouldn't bring them back until the band mixed the album in a way more to his liking.[2] Shortly after release of the album, Paul left the band, and he only appears in the first promotional video produced, "No Way Out." After the departure of Kantner the band lost the "Jefferson" moniker and morphed into Starship; there would not be another studio album released under the Jefferson Starship name until after Kantner reformed the band in 1992.
and this is interesting too
Produced by Ron Nevison, the album was arranged with the help of Peter Wolf, who had worked with Grace Slick on her solo album, Software. Wolf also contributed keyboard and synthesizer work to the album, although not an official part of the band. Peter Wolf (not the singer of the same name) and Ina Wolf also wrote the single "No Way Out", the first of many songs penned by the husband and wife duo that took "Starship" in a more commercial direction.
