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?
The best live act I remember seeing comes down to three, Dobbie Brothers "What Were Once Vices are now Habits" @ Cameron Indoor Stadium mid 70's maybe; Luicinda Williams "West" @ Carolina Theartre, Greensboro. Kansas "Leftoverture" @ Charlotte Colusium, late 70s.
Here's some great one's that no one has mentioned:
1. Al Jarreau / Look to the Rainbow
2. Grover Washington Jr. / Live at the Bijou

One more vote for:
ABB/Fillmore East
Feat/Waiting for Columbus
Dead/Europe 72
N.Young/Massey Hall
