Good sounding 70's live LPs...

If you liked Frampton try Live at the Fillmore by Humble Pie.
Also try Maximum Darkness by Man with special guest John Cipolina on Guitar.
Cheap Thrills by Big Brother and the Holding Company.
The box set by The Boss Live 75/85
and one of my favorite obscure recordings One Live Badger/Badger with ex keyboardist from Yes Tony Kaye.

The Grateful Dead live recordings from the era have good sound quality to my ears. But people either seem to like the Dead or to really not like the Dead. Good recordings don't matter if you hate the music.

Agree on the LF Waiting for Columbus. Peter Gabriel Plays live (1983). Anything live by the Neville Brothers.

Here's a guilty pleasure-Uriah Heep "Live". I think it came out in the late 1970s. Black cover with white letters. Bass and kick-drum sound amazing to me. Some of the songs are even good!

I almost forgot The Velvet Underground 1969 Live with Lou Reed. It came out in the 70's. The sound isn't great but it's the best you're ever gonna get for live VU.
