Metallica ,in their early days they were the Kings. Modern day , I have to disagree with Godsmack, if I wanted to hear Alice in Chains I'd listen to Alice in Chains. COC Rock hard, as do Pantera, Slipknot(wild live shows), Sepultura (Before Max Left), 40 Grit and Stuck Mojo. But my Fave Band of all time is KYUSS, Awesome music one of the most different sounding bands ever, the Guitarist, Josh Homme (now in Queens of the Stone Age with another ex KYUSS member Nick Oliveri, Aussies catch them at the Big Day Out) used to run his setup through a Bass Amp for some Extreme bottom end power. Just the humble of a metal fan of 14 years. BTW I am only 26.
