My most memorable ROCK moment

Further to comments about seeing great bands when they were somewhat unknown, I saw The Talking Heads at the Berklee Performance Center in Boston when their only well-known song was Psycho Killer (ca. 1976); the opening act was a band from Athens, GA called the B-52s. Great show. I also saw U2 at a rock club that seated about 400 just when they started getting alternative radio station airplay in the US and they were terrific as well.

How about Billy Joel in a high school auditorium in 1974 with an opening act on his first tour----a comedian named Billy Crystal.

BTW that was long before BJ turned into a joke himself.

Pink Floyd, "The Wall" concert. Bruce Springsteen and the E street band some time in the 80's. Rock Nirvana.

Stevie Ray Vaughan at Fitzgerald's, in Houston.

If your standard for "great" is arena rock, you missed the boat. There is no way a great player can really stretch out in an arena. Many times I heard Albert Collins, Lightin' Hopkins, BB King, John Lee Hooker, Albert King, and Alan Haynes in small clubs. Far more enjoyable and amazing than the Who, Stones, Led Zep, Eric Clapton etc. in big arenas, great as some of those shows were. I only wish I could have heard those guys before they made it big. John Lee Hooker, in particular, could get the place going so that every single person in the joint was boogieing along.
Some Grateful Dead shows were great. To the extent I remember them...
