BoozeFest2006: 1st post!!!!!

metalgore666beast: They sold out when they relased an album on cd, I can't believe they signed to a bigger label! vinyl---->cd

NilfheimGoatSlayer: Screw all metalcore and Nu-metal!

GraveLabour: Their leadsingers is hot though, I'd pee in her butt!

DeathCorpse69: Their last album was great, but the new one really sucks, mostly because I heard their bass player is gay...

Metalcruncher: Yeah they should have stayed on that unknown Polish label. Damn posers!
