Please do not confuse me with Schubert!
Rock was never metaphysical but visceral. Rock, rock n roll or whatever words you want to describe it, was always rebellious, at least the notorious side of it. It was always about lost love, cheating girlfriends, revenge, and redemption. Rock was seductive, particularly, to middle class suburbia angst. I wanted fast cars like the Beach Boys and Jan and Dean had. I wanted a GTO. I wanted girls and sex like the Rolling Stones promised. But perhaps by 1967 things changed, it became mainstream, the capitalists could make a ton of money off of it. We went from clubs, to arenas, to stadiums. To some extent the music became slower [beats per minute], even turgid, because the acoustics in stadiums back then were horrendously bad. [ not unlike why plainchant was so slow, not because they do not want to speed up things a bit, but the acoustics in cathedrals were ghastly with reverb! Machaut used this to his advantage!]. And what is truth, in a post modern world? Whatever gets the most applause.......;-)))
