Black Sabbath's "We Sold Our Souls for Rock and Roll" was the first CD I ever owned. I was hooked on Ozzy instantly.
Grohl is just pure talent. Nirvana, The Queens of the Stone Age, Foo Fighters, Them Crooked Vultures...Everything he touches is beautiful because he knows how to collaborate with other artists.
I don't even know where to start with Devin Townsend. He has such a beautiful mind and manages to be technically brilliant and still have heart. His vocal range is out of this world. If you listen to his screaming like in Strapping Young Lads and then take it over to Winter by the Devin Townsend Project? Guh. The range on that man and his guitar skills.
