I LOOOOOVEEEEEEE Grace and the Airplane, and the Marty Balin era of Jefferson Starship (though I do have a soft spot for 'Nothing's Gonna Stop Us Now' from the later 80's
)!
'Baron Von Tollbooth and The Chrome Nun' (Grace with Paul Kantner and David Freiberg) is excellent, along with the 'Sunfighter' album.
On the latter, Grace does an incredible song and vocal on a track called 'Silver Spoons' (about cannabalism of all things -
).
