by William RuhlmannAt the time this album was recorded, Jefferson Airplane had expanded from a rock group into something of a San Francisco collective of musicians and launched its own record label, Grunt, necessitating a flow of product. As a result, there was a flurry of releases by the Airplane itself and several offshoots, with each of these records featuring several members of the loose aggregation informally dubbed PERRO (the Planet Earth Rock 'N' Roll Orchestra). Papa John Creach, violinist for the Airplane and its spin-off group, Hot Tuna, was the leader on this set, which featured members of the Airplane (Grace Slick, for example, duets with Creach on the lead-off track, "The Janitor Drives a Cadillac"), Quicksilver Messenger Service, and the Grateful Dead. The result sounds like the Airplane records of the period, with a bit more of Creach's electric violin soaring over the proceedings.
