Good sounding 70's live LPs...

Good bass from live albums (vinyl) of the 70s includes:

ZZ Top - Fandango
Brand X - Livestock
Genesis - Seconds Out
Supertramp - Paris
Albert King - Blues Power
Outlaws - Bring It Back Alive
The Who - Live At Leeds (new remastered from Classic)
King Crimson - Red

From the 80s:
Peter Gabriel - Plays Live

I'm sure I'll think of a few more

Don't know if it is 70's, but Deep Purple Made in Japan is great. I also think Bob Seger "Live Bullet" is very good. I will have to think about this some more.

There's a nice one by the Allman Brothers... at the Fillmore, I think.

The 1978 double album "Waiting For Columbus" by Little Feat is one of the best, if not the best, live recordings.

Even the MOFI copy is decent but the original pressing on Warner Brothers is spectacular and the one to own.
