Many years ago there was a similar thread - but it was limited to vinyl bootlegs. I started this thread because my favourite one is on CD. And it is not a Zappa/Mothers concert, although I have a bunch of Zappa bootlegs of course...
So this is mine:
Genesis
Recorded Live At The Academy Of Music, New York City, 4th May, 1974
2CD Set
