Vol. 1: Unreleased (aka The Official Jay Dee Instrumental Series Vol.1: Unreleased) is an instrumental EP by the late Detroitrecord producer, Jay Dee (also known as J Dilla), released in 2002. The EP was compiled by Jay Dee and Waajeed, and is a collection of previously unreleased beats. Two of the tracks on the EP, "Busta" and "L.L.", are respectively named after Busta Rhymes, and possibly LL Cool J, which may indicate that Jay Dee had intended to shop these beats to them. Although Jay and Busta worked together on numerous occasions, he never worked with LL. It is also possible LL could stand for "Lonnie Lynn", the legal name of frequent Jay Dee collaborator Common. Also, it could be entitled 'LL' because it contains small LL Cool J vocal samples throughout. Vol. 1 is distributed by Bling 47 and is mainly available through their website. This release was followed by Vol.2: Vintage, three months later.
