Above is just one slice of “The Timeline” a rock-n-roll comic floating around the intertubes. Please view the whole thing here: http://ouchthatshot.com/the-timeline-the-full-rock-of-ages-comic/
Seemed to sum it up pretty well.
(Sum it up? Summit up? Climbing somewhere higher? Is rock going anywhere? I doubt it, but I’m ok with that. It’s just the folk music of our times, resonance dissipating with distance, sooner or later yelping a high-lonesome final cry, echoing from down in some holler. As ancient as oaks carved with the healed-over scars of young-lover’s initials. Lost off a forgotten path, brambled and disused. Waiting to be digitally discovered by the robots of NPR 2500, reminding young tots of the importance of endangered Beatles, Leppards, Byrds and Monkees.)
