Too many to list... Pink Floyd 1986 Maybe? There was one STP concert that sticks out (1994-1995) but that story is too long to go into. Also Dream Theater did a really great show once too for Scenes from a Memory (I've seen them 7 times) and Joe Satriani is consistently good seen him about 12 times. Also Aerosmith, Gun & Roses, Deep Purple in 1988 was lots of fun but not really for the music
