Best Live Album Ever...

Spent this afternoon listening to Genesis, "Seconds Out" album. Very good sound quality but amazing musicianship. Possibly my favorite live album ever. Also like Little Feat " Waiting for Columbus" and Van Morrison "Friday night in San Francisco" any other votes out there?
ABB Live at The Fillmore East!!!
Los Lonely Boys Live at The Fillmore is also a nice listen.
Many fine albums have already been mentioned- one which is often missed is Warren Zevon's 1981 "Stand in the Fire". Really captures the energy of the performers.
I agree with many of the above albums and I would have to add:
Bill Evans Waltz For Debby & Live at the Village Vanguard
Jackson Browne Running on Empty
Van Morrison Astral Weeks Live at the Hollywood Bowl
My new favorite live album is Pink Floyd's 1974 live performance of Dark Side. The live CD comes with the Experience and Immersion Editions from the 2011 remaster. The sound quality and performance is excellent. If you're a Pink Floyd fan this is a must.
