Top five live Rock And Roll Albums

Live albums generally suck, and ar a cash grab

anything by Gary Moore, Pat Travers, Solitude Aeturnus, Motörhead, Holy Moses. 

Any metal bands from the 80's, as this is when they wanted it more, and were hungry for fame, so the pressure they have is amazing!

SOME live albums are indeed a cash-grab, but as many do manage to capture the vibe of an artist's performance - like most of what lenmc2964 began this thread mentioning. 

Lucinda's Fillmore recording is a perfect example of how a live performance can energize a song. "Change The Locks" is an exercise in tone shift - the studio version strikes me as almost timid while the live version seems to emancipate.  It's a riff that Crazy Horse could be proud of as well. 

So far as 80's hair/metal bands go...well...

Live jazz recordings are an obvious exception - this is where those guys live. 

So many great records mentioned, so many I would agree, so many I haven't heard and will listen (Tidal!)

One to add . . . Leon Russell Live.

Leon never stops, just like when I saw him in his prime. Non-stop rock'n'roll . . . it almost wears you out. Not like his studio albums. Unfortunately, sonics aren't great.

A top 10 would include;
Leon Russell
Bob Seger

Not necessarily in best to worst but you can't go wrong here:

Allman bros live at FM
little Feat Waiting for Columbus
