Good sounding 70's live LPs...

Tom Waits, "Nighthawks at the Diner" was recorded live in the studio with an audience and sounds brilliant if that counts...

Neil Young's "Live Rust" and "Rust Never Sleeps" are also good examples of live recording.

Genesis - Live, the earlier tunes
Loggins & Messina - On Stage (2LP), nice retrospective
War - Live (2LP), killer sonics and extended jams
David Bromberg Band - How Late'l You Play Til'? (2LP)
Simon & Garfunkel - Concert In Central Park (2LP) excellent

These should keep your foot tapping for a while...good listening,

The 3-lp 'Yessongs' by Yes is notoriously not well-recorded, but the performances are amazing.

Wally Heider recordings are very good. Marshall Tuckers two live sides from "Where We All Belong" are excellent. So is the music. Way more rock/jammed out tunes averaging 10 minutes long. Brand X "Livestock" is good as mentioned above. Kenwood Dennard plays drums on 3 tracks too in place of Collins. I like "Babylon By Bus" better than "Live" by Marley. I cn't think of any more. Trower live is a great performance but not a good recording. Billy Cobham/George Duke Band "Live in Europe" with a young Scofield and Alphonso Johnson on bass/stick is good.
