The 59-year-old Uptown Records founder died earlier this month from heart disease-related issues, with his life celebrated at Vander Plaat-Caggiano Funeral Home in Fair Lawn, New Jersey, at the weekend. Following the service, Harrell was laid to rest at the nearby George Washington Cemetery.
Mariah and Mary were joined by other famous faces including executives L.A. Reid and Lyor Cohen, as well as comedian Chris Rock, according to local reports.
During the service, a host of Harrell's friends remembered the late star, with musical performances coming from Jodeci and gospel singers BeBe and Cece Winans. Blige, Rock and Cohen all spoke during the funeral, alongside Harrell's son Gianni Credle-Harrell.
The legendary music executive, who was born in Harlem and raised in the Bronx, New York, is best known for founding Uptown Records, which became one of the most popular hip-hop and R&B labels during the 1990s.
The label was responsible for the success of stars including Jodeci, Guy, Heavy D and the Boyz, and Notorious B.I.G.. It also led the way in the sub-genre of New Jack Swing, after signing super-producer Teddy Riley of Guy and Blackstreet fame.
