anything ranging from extremely underground bands that have toured, the most mainstream tour that's happened recently was anthrax touring with soilwork and killswitch engage which was 18+. for fuck's sake, machine head and slipknot (february) performed over age shows, i think nightwish are as well.

i've been to two out of the three underage tours that have happened since i started liking metal, opeth (3/2004), deeds of flesh (7/2004) and in flames (didn't go, 9/2004) and since in flames there's been one underage gig at all (blood duster plus support).

there is a temporary ban on underage music because a bunch of (OVERAGE) lebanese cunts, fucked a security personnel over at an underage gig last year. it's ridiculous, but hey that's life.
