top 3 would be:
1. Toadies- Shadow Canyon - Spring 2001
2. The Nixons - Tap - Fall 2000 (?)
3. Blue October/Bowling for Soup/Sponge - Spring 2001 (met my now wife at that show. She was there for Blue, I was there for Bowling, and my buddy that knew her was there for Sponge) This show was 2 nights before the Toadies concert, on a Tuesday night. The Toadies concert was Thursday night before Good Friday. I rode up to Dallas with my freshman year roommate to spend Easter weekend with his family, and I couldn't hear him the whole drive up Friday afternoon because my ears were still ringing. Apparantly after the Toadies concert, when we were at Taco C, my now wife saw me and tried to say hi (we had met 2 nights earlier at the above mentioned concert), but i was so deaf from the show (front row left side of stage), that I didn't hear her.
I'll also throw a Vibe show in there as well (only because I have never seen a band more into a show with only about 100 people in the crowd) This would have been at Shadow as well...can't remember when..sometime in 2001-2002 probably.
