thats hard..... i don't know, there are so many..... uuuuhhhh...... i'd have to say classic is metalica and today is slipknot, mudvayne, korn, god smack, static-x, flaw, shadows falls, killswitch engage, rob zombie
see this **** is hard, they all have their highlights, you cant jus choose one
BUT my all time favorite is korn but i dont know im getting a headake thinking about this
