Ma Dukes Yancey readies “iconic” collection.

Since J Dilla‘s tragic passing in 2006, there has been no shortage of posthumous releases, whether sanctioned by the Yancey family or not. Soon, there will be another addition to the discography with The King of Beats: Ma Dukes Yancey Collector’s Edition.

“This project came about by a lot of soul searching and meditation as to what can I do now that my son has so many bootleg projects out by unknown artists without my approval,” Yancey tells Rolling Stone. “Now that I’m out of mourning and full of insight and feeling my son’s energy radiate around me, I wanted to do something different but iconic; Something that people would preserve and relish for a lifetime that spoke quality.”

The box set includes four 10″ vinyl records featuring music from Jay Dee’s Batches collection, a cassette that includes 4 unreleased “Lost Scroll” tracks, a 3″ floppy disk that contains an unreleased Dilla production that is formatted for the E-Mu SP-1200 machine. The SP-1200 — a piece of gear favored by the producer — also inspired the box set’s design.

Pre-orders will begin on Tuesday, June 24 at 10pm, with the collection set to ship on August 26. Head to the collection’s website for more details. Stream ‘Filth’ below for a taste of what to expect.

Last year, FACT’s Laurent Fintoni wrote about J Dilla and why posthumous releases miss the point; Tom Lea spoke to Ma Dukes back in 2012 about the topic. For more on the E-Mu SP-1200, Neil Landstrumm included it in his feature on crucial studio gear.
