An interesting summary of the distinctive sounds and noises that shaped rock and roll. I never noticed this before, but "You Really Got Me" by The Kinks has a really odd relationship between the power-chord guitar part and the drum part. When the drums come in, the guitar part seems to shift but doesn't. Sort of an audio illusion, I guess. I have it on good authority that it starts on the "and of four," which I guess explains the phenomenon. Or, would explain it if I understood these things.
