Irv Gotti, the music producer who created hits for Ja Rule, Ashanti, DMX and Jennifer Lopez, has died at the age of 54. Best known as the founder of the record label Murder Inc., his signature style of blending hip-hop beats with smooth R&B melodies shaped the sound of the charts in the late 90s and early 2000s.

Before launching Murder Inc. in New York City in 1998, Gotti worked as an A&R at Def Jam, where he helped bring DMX, Jay-Z and Ja Rule to the label. Under the moniker DJ Irv, he produced the song “Can I Live” from Jay-Z’s 1996 debut, Reasonable Doubt.
