Rare Dylan tracks due next month

The Bob Dylan album that’s coming out Aug. 30 from Sony’s Columbia/Legacy label will be a bonanza of rarities, with 26 of the 28 tracks on the two-disc set previously unreleased, including a 1959 recording that’s believed to be the first original song Dylan ever recorded, “When I Got Troubles.”

The album, “No Direction Home: The Soundtrack -- The Bootleg Series Vol. 7,” is a companion to the Martin Scorsese-directed profile of Dylan that will air on PBS on Sept. 26 and 27.

Other tracks include a live version of Woody Guthrie’s “This Land Is Your Land” from 1961; the first complete take of “Mr. Tambourine Man,” with Ramblin’ Jack Elliott; and an outtake from “The Freewheelin’ Bob Dylan” sessions called “Sally Ann.” The set also includes several live tracks and nearly a dozen alternate takes from his mid-’60s albums “Bringing It All Back Home,” “Highway 61 Revisited” and “Blonde on Blonde.”
