Irv Gotti, the music executive, songwriter and producer behind the reign of hip-hop and R&B stars Ja Rule and Ashanti in the early 2000s, has died. Gotti, the music mogul who co-founded Murder Inc. Records, was 54.

Irving Lorenzo Jr.—known to the music world by his professional name, Irv Gotti—has died. Through his work, first for Def Jam Records, and then as the co-founder (with his brother Chris) of Murder Inc.

Following his tenure as A&R at Def Jam, Gotti founded Murder Inc. with his brother Chris Gotti in 1998 and released Ja Rule’s debut album “Venni Vetti Vecci” the following June. That album became a massive smash for both Ja Rule and Gotti, who executive produced the album and helmed every song on the project.
