You’re a good man Seamus!!
My first was Sepultura, Pantera and Biohazard in 94. My algebra teacher took us. Last one was Slayer in June 2011.
My favorites were the first one of course, AC/DC in 96, Kiss in 97, Iron Maiden in 04, Ozzfest 97 and 98.
I used to play in bands, so we were at a ton of shows.
