I've seen too many shows and bands to list, although I would hardly call them "concerts". I just see punk bands at pubs and stuff on some weekends. I think the only big arena concert I've been to was Slayer, but I was unsuccessful at getting in (I didn't have the money and tried to sneak in). Anyway I gave up, but the two friends I was with ended up getting in to see the last half of Slayer! Lucky bastards.
