As always, the revolution of which I speak isn't apparent until the fighting is done. We don't know what current music will stand the test of time, because the time hasn't passed. But we have a pretty good idea, in hindsight, who led the revolutions of prior periods.
There was something magic about Great Britain in the 60's and 70's, as far as rock music is concerned. Everyone lived within shouting distance of everyone else, and the entire panoply of world-class talent shopped in the same music stores as the weekend duffers, drank beer in the same pubs, and listened to each other in the same venues. I'm amazed at how groups got "discovered" by playing gigs in the London suburbs that were attended by the same music press and by those who became rock legends that in the U.S. would never have seen such groups. I don't see that same nexus of national talent in the history of groups in the U.S., and it seems American groups required a more purposed talent-spotter.
