Good sounding 70's live LPs...

I have to say that the Supertramp Live in Paris and the Allman brothers band, Live the Philmore East (classic 200gram) are one of the best live LP's I have heard. I need to dog out the waiting for Columbus by Little Feat and give that a spin.

Bowie Live...outstanding album on many counts. Get it, put on "Cracked Actor", and crank it up. This and Allman Bros. Line at Filmore East...the best of the best.

"Bob Marley Live"

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,
