My idol is probably Metallica, as a whole band. I just think that over the years they have been constantly the best metal band. I just think they absolutely rule. And if anyone hasnt seen them live.....do yourself a favour and get to a gig. Because there is nothing like it.
I mean, I have seen so many metal bands, Slayer, Megadeth, Motorhead, Lamb of God, Shadows Fall, System of a Down, Slipknot, Killswitch Engage, Black Sabbath. They were all good, but nothing compared to Metallica.
At the Metallica gigs, the atmosphere is just HUGE. And they have been my idols for the last god knows how many years. I think they always will be too!
As for individual guitarists, I would have to say Yngwie, or Paul Gilbert as my idols. But personally I am more of a "band" type person.
