There has scarcely been a new phenomenon that transformed the culture which hasn't been relentlessly mocked at the outset. (That Dave Eggers was immediately accepted by the establishment showed he wasn't the genuine article.)
This includes Elvis and the Beatles, the last real wave of transformation.
I've given the example often of Elvis's first appearance on the Tommy Dorsey Show with the other two members of his combo (related in Last Train to Memphis) when they were still unknown in New York. Highly-skilled jazz drummer Buddy Rich looked with contempt at the ill-clad yokels. "These guys can't even play their instruments!" he howled. Yet within two years Dorsey and Rich were swept out of the picture by the tidal wave of rock n' roll-- which reached, better than they, strains of feeling and truth within the American people.
