Fatman Scoop died after reportedly collapsing during a concert Friday night in Connecticut.
His family confirmed his death in an Instagram post on Saturday. He was 53.
“It is with profound sadness and very heavy hearts that we share news of the passing of the legendary and iconic FatMan Scoop,” a post on his Instagram page read. “Last night, the world lost a radiant soul, a beacon of light on the stage and in life.”
The rapper and hype man, whose real name is Isaac Freeman III, was performing at the Green and Gold Party summer concert in Hamden, about six miles from New Haven, when he suffered a medical emergency on stage.
The town’s mayor said he was taken by ambulance to the hospital.
Video posted on social media showed a shirtless Fatman Scoop hyping up the crowd at the Town Center Park shortly before collapsing. The event was scheduled to happen last month but because of weather, it was postponed to Friday night.
Fatman Scoop has worked with some of the biggest musicians, including on Missy Elliott’s “Lose Control” and Mariah Carey’s “It’s Like That.”
“FatMan Scoop was not just a world class performer, he was a father, brother, uncle and friend. He was the laughter in our lives, a constant source of support, unwavering strength, and courage,” his family wrote. “FatMan Scoop was known to the world as the undisputed voice of the club. His music made us dance and embrace life with positivity. His joy was infectious and the generosity he extended to all will be deeply missed but never forgotten.”
