Have you ever been to a metal concert? Anyone who plays that fucking loud has got to be deaf.
Yeah, you pretty much have to wear ear plugs, or there is no real way to enjoy a metal concert. The people who mosh right up next to the stage are fighting for the title of "group that consists of the most tools". Children of Bodom was probably the quietest metal band I ever heard live, and they were still a little too loud for my tastes.
Oh yeah, and actually, the older metal musicians I know.. They actually are deaf from years of playing next to max volume amps without wearing any ear plugs.
Which is fucking masochism if you ask me. sheeesh
