James Dewitt Yancey (February 7 1974–February 10 2006), better known as J Dilla, or Jay Dee, was an acclaimed Hip-Hop producer who emerged from the mid-1990s underground Hip-Hop scene in Detroit, Michigan. He began his career as a member of the group Slum Village, and was also a driving force in the production trio The Ummah. Yancey started his career under the name "Jay Dee" (based on his initials) but used the name "J Dilla" from 2001 on. Many critics believe J Dilla's work to have had a major influence on his peers, and that he embodied the neo soul sound, playing a defining yet understated role during the sub-genre's rise (roughly from the mid-90s to the early 2000s). J Dilla was often dubbed "your favorite producer's favorite producer", and was highly regarded by mainstream artists and producers such as Common, Kanye West, A Tribe Called Quest, Just Blaze, Busta Rhymes, Pharrell Williams,and ?uestlove. .
