Between his debut as a member of the Irish band Them and his celebrated 1968 album Astral Weeks, Van Morrison recorded a series of songs for Bang Records. His output during his stint for the label pretty much amounted to his 1967 solo debut album, Blowin' Your Mind!, which contained the Top 10 single "Brown Eyed Girl."

The original album's eight tracks plus many others recorded during the sessions will be collected on a new three-disc set, The Authorized Bang Collection, which comes out on April 28.

Much of this material has been repackaged over the years, but this new set includes some previously unreleased alternate takes of songs that showed up on Blowin' Your Mind! Elsewhere, The Authorized Bang Collection also compiles the "Contractual Obligation Session," a recording date in which Morrison burned through 30 fragments of songs to fulfill his time with Bang. He left the company for Warner Bros. shortly after.

You can see the full track listing for The Authorized Bang Collection below.

Legacy Recordings says the upcoming album is "the first official comprehensive anthology ever assembled" on Morrison's Bang material. In addition to the first CD appearance of the original stereo mix of the album, the collection features rare mono mixes of songs recorded at the LP sessions, including an early take of "Madame George," which appeared on Astral Weeks a year later.

Included on the second disc of rarities is the original mono single mix of "Brown Eyed Girl," as well as alternate takes of "T.B. Sheets," "Midnight Special" and another song that ended up on Astral Weeks, "Beside You."
