Bob Dylan is an American singer-songwriter, author, and visual artist who has been a major figure in popular culture for more than 50 years. Much of his most celebrated work dates from the 1960s, when songs such as "Blowin' in the Wind" and "The Times They Are a-Changin'" became anthems for the civil rights and anti-war movements. His lyrics during this period incorporated a range of political, social, philosophical, and literary influences, defied pop music conventions and appealed to the burgeoning counterculture.
Following his self-titled debut album in 1962, which mainly comprised traditional folk songs, Dylan made his breakthrough as a songwriter with the release of The Freewheelin' Bob Dylan the following year. The album featured "Blowin' in the Wind" and the thematically complex "A Hard Rain's a-Gonna Fall". For many of these songs, he adapted the tunes and phraseology of older folk songs. He went on to release the politically charged The Times They Are a-Changin' and the more lyrically abstract and introspective Another Side of Bob Dylan in 1964.
