Murder Inc. was an American hip hop supergroup formed by American music executive Irv Gotti, in 1995. The trio was composed of three of the most prominent rappers in the music industry at the time, East Coast hip hop artists Jay-Z, DMX, and Ja Rule. The trio first appeared on fellow New York-based rapper Mic Geronimo's song "Time to Build". The trio even went on to appear on the cover of the June 1999 issue of American hip-hop magazine XXL. "Murder Inc." was rebranded by Irv Gotti in the namesake record label he co-founded in 1998, in which Ja Rule was signed. From Wikipedia
