I listened to 311 back then, and I started listening to Meshuggah back then too because 311's guitarist said in an interview they were the heaviest band ever.
barely any music at all... i think when i went into 7th grade was when i started to listen to music more.. and at that time i was only listening to The Offspring, Limp Bizkit (kill me ), and Green Day
i didnt discover metal until late in 8th grade (I'm 17 now, going to be a senior in HS already next year hehe)
