Some of the music is wonderfully loopy and strange. Crown of Creation has an absolutely unique love song: Triad, where Grace Slick is asking two guys, why can't we just be three? But the title track is a bit anemic compared to the live version that appears on the band's final album 30 Seconds Over Winterland.
Volunteers has one absolutely amazing track on it (although I do like the title track): their version of the Crosby-Stills song Wooden Ships.
Irrelevant personal detail: If you look at the back cover of 30 Seconds Over Winterland, you will see the lightshow graphics projected above the band. This was the Heavy Water Lightshow, which in later years did lightshows at a planetarium out west. I was a student intern in the planetarium and worked for the lightshow as an usher one summer. They used Wooden Ships on the soundtrack. I never got tired of the song.
Jefferson Airplane had their moments, but the group was simply too diverse in their interests to keep it going...
I just went over and checked by original vinyl of the "Volunteers" album. I had forgotten that David Crosby and Stephen Stills perfomred on there, along with Jerry Garcia. Also have my "Surrealistic Pillow" and "Bless Its Pointed Little Head" albums, although I don't think I have listened to them in over 30 years. Now "3/5 Of A Mile In Ten Seconds;" there's one that isn't for everybody.
