i have to add some on the origin of metal! Black, death, thrashmetal has in fact much more in common with classical music than with blues! the more chromatic composititions ar VERY different from pentatonic blues scales! of corse early metalbands like black sabbat or even iron maiden had more of a rock influence, but bands in the black/death/speed/thrash genre and especially folk- or vikingmetal have more resemblence towards classic music or european folktunes! and if you see it in another way, black men might invented blues, but the instruments it was played on like the guitar are clearly european instruments! oh, and crap like britney spears or destiniy's child are not really black genre icons, they're more like todays non-individual massconsumer brats, which is at any rate VERY black influenced! just turn on MTV, the first you'll see will be some though black "gangstas" aping around in bent posture and redicilous clothing!
