Inspired by Dilla's beloved hometown, Motor City is a collection of rare and unreleased Jay Dee instrumentals, hand-selected and sequenced by Ma Dukes. Conceived as a "letter" to her son, Motor City is packaged in a limited-edition mailing envelope, complete with a handwritten message from Ma Dukes to J Dilla inside. Both CD and vinyl formats also include access to an exclusive mix of the album by Dilla's close friend J Rocc, a world-renown DJ and founder of the Beat Junkies.
