Elijah Wald Bob Dylan

On the evening of July 25, 1965, Bob Dylan took the stage at Newport Folk Festival, backed by an electric band, and roared into his new rock hit, "Like a Rolling Stone". The audience of committed folk purists and political activists who had hailed him as their acoustic prophet reacted with a mix of shock, booing, and scattered cheers. It was the shot heard round the world - Dylan's declaration of musical independence, the end of the folk revival, and the birth of rock as the voice of a generation - and one of the defining moments in 20th-century music.
