American record label formed by Jefferson Airplane on August 7, 1971, as an outlet for their own albums and side projects like Hot Tuna and solo recordings by band members, as well as other San Francisco Bay-area bands. The label was run by the band members and their manager, Bill Thompson (3). The label was deactivated in 1987, coincidentally fitting in with the de-evolution into commercial Top 40 pop-rock that the by-then Starship (2) had taken. All Jefferson Airplane/Jefferson Starship/Starship material released on Grunt has been reissued on parent label RCA.

Initially a subsidiary of Afterthought Productions Corp., then RCA Records.
