all i can say is fuck the metal police. Seriously, whats so wrong about having an open mind to music? Let alone who cares if a band is popular or not.
Iron Maiden? Pantera? Slayer? Judas Priest?
all metal bands that are still popular
if anyone is still stuck in their whole "closet band" phase its time you grow the fuck up.
Lamb of God are here to stay and there is nothing you can do about it
