He produced the majority of Common's "Like Water For Chocolate" cd, which is still my favorite Common cd. U can't even front on "The Light" from that cd. Also, remember how Q-Tip's "Vivrant Thing" used to bang in the clubs when it dropped. That was J. Dilla. He was a very versatile producer. Most producer's that are into Jay Dee's music know how intricate many of his productions were. They may sound simple, but they weren't simple to make. He made sampling an art. Jay Dee changed alot of kats whole approach to beatmaking. It's just ashame he didn't get his just due while he was still alive. Check out Dilla's discography here and 2 of my favorite Jay Dee productions below.
Slum Village - Climax
J Dilla - Won't Do
(Released after his death - That's his brother playing him in the video)
Peep how he sampled and chopped up The Isley Brother's "Footsteps in The Dark"
