Label launched by Jefferson Airplane in 1971 as an outlet for their own albums as well as side projects like Hot Tuna and solo recordings by band members. 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 have been reissued on parent label RCA.
