Robert Zimmerman legally became Bob Dylan on August 2, 1962. The folk singer has noted that he was influenced by the poetry of Dylan Thomas and chose the moniker in homage to the poet. Later this month, Columbia Records will release "Another Self Portrait" (1969-1971) containing 35 previously unreleased tracks from the original "Self Portrait" and "New Morning" recording sessions. The collection will be issued in both a 2-disc set and a 4-disc deluxe box set.
