Saw an unknown band called Rage Against the Machine (and some other band?) open for House of Pain at the Troc in Philly during the winter of 1992. Great show and still the only concert I went to where the sprinklers went off in the middle of the show...and no they didn't stop for a second!

1982
 

Judas Priest/Iron Maiden Cobo arena in Detroit. I was 13. Yes, it was as good as you might think it was. My hearing didnt come back for 3 days.

My first concert was supposed to be Red Hot Chili Peppers and Foo Fighters March 24, 2000. But I somehow won tickets to the Creed concert for March 23, 2000.
So embarrassing.. first concert: Creed.
A story that I won't be telling the kids.

I'm sorry Sir!

My first one was Garth Brooks. Some guy in a white suit was playing piano when it started and then Garth came out of a hole that opened up in the stage. I thought it was a pretty cool entrance at the age of 10.

First show was my friends band,first big show was Radiohead in 2002 i think.

I went to a Rage concert, lasted about 15 minutes, police shut it down

First ever parents took me to was June Jam and saw Alabama in their hometown and the first I saw on my own was System of a Down(before they blew up like they are now) who opened up for (the greatest ever) Rage Against the Machine in Nashville!!!!

Rush - 1985 Or 6 - Power Windows Tour.

my first show was Styx, for Pieces of Eight. April Wine opened for them. I was 14 at the time.
