Bob Dylan (born Robert Allen Zimmerman; May 24, 1941) is an American singer-songwriter and musician who has been a major figure in music since the 1960s. Much of his most celebrated work dates from the 1960s when he was an informal chronicler, and an apparently reluctant figurehead of social unrest. A number of his 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. His early lyrics incorporated a variety of political, social and philosophical, as well as literary influences. They defied existing pop music conventions and appealed hugely to the then burgeoning counterculture. Initially inspired by the songs of Woody Guthrie, Robert Johnson, Hank Williams, and the performance style of Little Richard, Dylan has both amplified and personalized musical genres, exploring numerous distinct traditions in American song—from folk, blues and country to gospel, rock and roll, and rockabilly, to English, Scottish, and Irish folk music, embracing even jazz and swing.
