J Dilla

James Dewitt Yancey was born on February 7, 1974, in Detroit, Michigan, and raised on the city's east side, later coming of age in the Conant Gardens neighborhood. Music surrounded him from the cradle: his father, Beverly Dewitt Yancey, was a jazz bassist, and his mother, Maureen "Ma Dukes" Yancey, was a former opera singer. By her account, the child could match harmony before he could speak.

Working under the names Jay Dee and later J Dilla, he rose from Detroit's mid-1990s underground as a member of Slum Village and a founding figure of the Soulquarians collective. Mastering the Akai MPC, he built a body of production for A Tribe Called Quest, Busta Rhymes, Common, De La Soul, The Pharcyde, Erykah Badu, and D'Angelo, among many others.

His signature was a deliberately unquantized, human "time-feel" — drums that leaned and lagged against the grid — a rhythmic language that reshaped hip-hop, neo-soul, and beyond. His instrumental album Donuts, released three days before his death, became a touchstone of the form.

J Dilla died on February 10, 2006, at the age of thirty-two, from complications of thrombotic thrombocytopenic purpura and lupus. His drum machine now rests in the Smithsonian, his rhythms are studied in universities and honored each Dilla Day. May his name be spoken with the reverence owed a true architect of sound.
