 The 1969 Woodstock Festival in New York state became a symbol of the movement, although the 1970 Isle of Wight Festival drew a larger crowd.Some believe the era came to an abrupt end with the infamous Altamont Free Concert held by The Rolling Stones, in which heavy-handed security from the Hells Angels resulted in the stabbing of an audience member, apparently in self-defense, as the show descended into chaos.The 1960s saw the protest song gain a sense of political self-importance, with Phil Ochs's "I Ain't Marching Anymore" and Country Joe and the Fish's "I-Feel-Like-I'm-Fixin'-to-Die-Rag" among the many anti-war anthems that were important to the era.
