Bob Dylan
Bob Dylan was a freewheeling songwriter who lived to travel. He was a "counterculture" musician, and most of his songs were anthems for other free spirits. "These times They Are a-Changin" was viewed as pretty political. Dylan was also a talented poet who became the first musician to win the Nobel Prize in Literature.
