So many greats to choose from. Listed randomly.
Live at the Fillmore East - Allman Brothers
Waiting for Columbus - Little Feat
One More From the Road - Lynyrd Skynyrd
Live 1966, The "Royal Albert Hall Concert - Bob Dylan
Band of Gypsys - Jimi Hendrix
Killer albums. I would have included Little Feat in my list if I'd remembered it
These lists are fun but i have difficulty narrowing them down. I did not even include favorites such as Rock of Ages (as you did), Young's Live Rust (he was represented otherwise, however), Focus' Live at the Rainbow and The Who's Live at Leeds.
