Just for curiosities sake, I was wondering if there were any metalish songs before Black Sabbath? Basically whether Sabbath just pulled this musical style out of thin air, with nothing like it in terms of heaviness and brooding doom other than perhaps classical music. I was pondering this question, and came up with Iron Butterfly, and King Crimson's song 20th Century Schizoid Man on the In the Court of the Crimson King record. Anyone else have any ideas?
