Yep he collaberated on a lot of phenomenal artists records: "He leaves behind a body of work which will be loved and rediscovered for years to come. His most recent album "Donuts" on February 7th, the day of his 32nd birthday. Two other projects, "The Shining" (BBE) and "Jay Love Japan" (Operation Unknown) are completed. Other production work has been completed for artists Madlib, Busta Rhymes, Ghostface Killah, A.G., Visionaries, Truth Hurts, Phat Kat, MF DOOM, Skillz, and Frank N Dank.
You can check his myspace here: www.myspace.com/jdilla to hear some of his new record (erm sorry hun, not feelin the new one) but champion sound is supposedly sick. I haven't heard the whole album, but champion sound IS one of my all time fav songs. Man..32 years old. Tragic!
