J Dilla was an absolute machine of a producer, creating more music than his lifetime could retain. Posthumous tracks continue to surface from the late Dilla, including particularly unique combinations with him and other well known recording artists. Just yesterday, the Dilla family announced Motor City, a new posthumous release that spotlights Dilla’s roots in the Detroit underground hip hop scene.The album is due out on April 21st, and was put together by Ma Dukes, featuring hand-picked selections from the Dilla collection. Among those is a take on Biggie’s song “Juicy,” complete with a previously unreleased beat laid down by Dilla himself. The beat was provided by Dilla’s own collaborator J Rocc, and the track was released as a sampler for the upcoming Motor City collection.Take a listen to the new single, and be prepared for more grooving Dilla beats to come.
