Bob Dylan has been a major figure in popular music for five decades. Much of Dylan's most celebrated work dates from the 1960s, when he became an informal chronicler and a reluctant figurehead of American unrest. A number of his songs, such as "Blowin' in the Wind" and "The Times They Are a-Changin'", became anthems of the anti-war and civil rights movements. His most recent studio album, Modern Times, released on August 29, 2006, entered the U.S. album chart at number one, and that same year was named Album of the Year by Rolling Stone magazine. While expanding and personalizing musical styles, he has shown steadfast devotion to many traditions of American song, from folk, blues and country to gospel, rock and roll and even jazz and swing. Dylan has earned Grammy, Golden Globe, and Academy Awards, and has been nominated several times for the Nobel Prize in Literature.
