Bob Dylan (born Robert Allen Zimmerman; May 24, 1941) is an American singer-songwriter, musician, poet and painter who has been a major figure in music for five decades. A number of his songs, such as "Blowin' in the Wind" and "The Times They Are a-Changin'," became anthems for the anti-war[ movements. Dylan's early lyrics incorporated political, social and philosophical as well as literary influences. They defied existing pop music conventions and appealed hugely to the then burgeoning counterculture. , he has explored many traditions of American song, from folk, blues and country to gospel, rock and roll and rockabilly to English, Scottish and Irish folk music, and even jazz and swing.
