Dylan reveals 'Another Side' and 'My Back Pages'

Fifty years ago today, in the wee hours of the morning, Bob Dylan finished recording his fourth studio album, "Another Side of Bob Dylan." He recorded all the tracks in one marathon session, ending with this song "My Back Pages" at 1:30 a.m. This album has been described as a transition between the topical acoustic folk music of his first few records and the stream of consciousness imagery that marked his electrified albums.
