The Authorized Bang Collection is a compilation album by Van Morrison containing every track that Morrison recorded for Bang Records in the 1960s. It was released on April 28, 2017, by Legacy Recordings on the Bang label.[1]
The first disc, The Original Masters, contains 17 tracks including every track from Morrison's debut album Blowin' Your Mind!. The second disc, Bang Sessions & Rarities, contains alternate takes from the Bang sessions. The third disc, Contractual Obligation Session,[2] contains demos Morrison recorded to fulfill his contractual obligations to Bang; he recorded them in one session on an out-of-tune guitar, with lyrics about subjects including ringworm and sandwiches.[3][4] The throwaway compositions came to be known as the "revenge" songs,[5] and remained officially unreleased until this collection was compiled.[6]
