James Dewitt Yancey (February 7, 1974–February 10, 2006), better known as J Dilla or Jay Dee, was an American hip hop producer and MC, who emerged from the mid-1990s underground hip-hop scene in Detroit, Michigan. He began his career as "Jay Dee" 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 [1], and he perhaps 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).
