Lots of great bands mentioned here, Spirit, Mountain who I saw several times back in the early 70's. Jefferson Airplane, Traffic. I rediscovered The Stooges and early Grand Funk while living in Lima, Peru several years ago. I saw The Stooges in 1969 but never saw Grand Funk. I love Mel Schacter's bass playing and sound on the first 5 or 6 LP's especially the 2nd album, the red one with the J bass on the cover. I could blast that album all night.
Same for The Stooges, especially the Raw Power stuff, I have almost all the bootleg stuff and legitimate releases. That band rocked, Raw Power has to be the most powerful and primitive stuff ever released on record. I have all three versions, the Bowie mix on LP, The Iggy mix on CD and the rough mixes, plus all the live stuff, the rough mixes that was supposed to be the second album which would have been killer. I actually like the Bowie mix the best on most songs because it's got more bottom, Iggy really unleashed it's power though, scary good.
