Jam Master Jay

Bio

Jam Master Jay is the architecture. Run is the front of the stage. DMC is the writer. Jay is the reason the whole thing sounds the way it sounds.

Born Jason Mizell in Brooklyn in 1965, raised in Hollis, Queens, he came up DJing at block parties as a teenager. By 1982 he was running with Run and DMC. By 1983 he was on the Run-DMC debut single. He never moved off the turntables. The way an old guitar player might say the band only works because they have the same drummer for thirty years is the way you should think about Run-DMC and Jay.

He had a couple of things working for him as a DJ. He had timing. He had discipline. He had a specific physical style on stage — the wide stance, the head-back posture, the visible enjoyment — that most DJs of the era did not have. On the early Run-DMC records the producer credit usually goes to Russell Simmons and Larry Smith, but Jay's contribution is the live performance: he is the person making sure that what happens on stage in front of 20,000 people sounds anything like what got recorded in the studio.

After Raising Hell, Jay became Run-DMC's de facto musical director. He pulled in production duties. He produced for Onyx, the early-1990s Queens trio he signed and shepherded. He produced for 50 Cent very early in 50's career, on demos that did not chart but did get 50 in front of Eminem. There is a not-small argument that 50's whole subsequent career traces back to Jay's mentorship.

On October 30, 2002, Jam Master Jay was murdered inside his own recording studio in Jamaica, Queens. He was 37. He was sitting on a couch with his bookkeeper when somebody walked in and shot him in the head. The case stayed open for two decades. In 2024, two men, Karl Jordan Jr. and Ronald Washington, were convicted in federal court of his murder. The motive that came out at trial was a drug deal: a cocaine consignment that Jay had been involved in, that had gone bad, that had been festering between him and Jordan for years. It was not the version of the story anyone had wanted to be true.

What he was: the architecture. What he is now: every hip-hop DJ from the late 1980s forward took something from him. Inducted into the Rock & Roll Hall of Fame with Run-DMC in 2009, posthumously. The plaque does not say enough.
