Bob Dylan is an American musician, singer-songwriter, artist, and writer. He has been an influential figure in popular music and culture for more than five decades. Much of his most celebrated work dates from the 1960s, when he was an informal chronicler and a seemingly reluctant figurehead of social unrest. A number of Dylan's early songs, such as "Blowin' in the Wind" and "The Times They Are a-Changin'", became anthems for the US civil rights and anti-war movements. Leaving behind his initial base in the culture of the folk music revival, Dylan's six-minute single "Like a Rolling Stone" radically altered the parameters of popular music in 1965. His mid-1960s recordings, backed by rock musicians, reached the top end of the U.S. music charts while also attracting denunciation and criticism from others in the folk movement.
Dylan's lyrics have incorporated a variety of political, social, philosophical, and literary influences. They defied existing pop music conventions and appealed hugely to the then burgeoning counterculture.
