"Rock is black music" is so incredibly overblown. The influence of blues in rock was momentary and by the time you get interesting rock like Yes, King Crimson, Led Zeppelin post-LZII, etc., that influence is almost completely gone, and in any case is completely dwarfed by the influence of English folk, classical, art-music, and insular genre-internal influences. And blues itself was the result of American blacks imitating the European folk tunes of the continent. But no one says "blues is just stolen white music". The whole thing is retarded white guilt bullshit.
