M.O.P. is an American hip hop duo composed of East Coast rappers Billy Danze and Lil' Fame. After years of mostly underground success, they gained more mainstream recognition in 2000 with the song "Ante Up", which would become their biggest hit. The group has frequently collaborated with DJ Premier and is part of the Gang Starr Foundation. Fame sometimes produces under the moniker Fizzy Womack, and has produced tracks on every M.O.P. release since 1996's Firing Squad, as well as work for other artists including Kool G Rap, Teflon and Wu-Tang Clan.

Christopher Edward Martin, known professionally as DJ Premier, is an American DJ and record producer. He is considered one of the greatest hip hop producers of all time. He was half of the hip hop duo Gang Starr—alongside the rapper Guru—and presently forms half of the hip hop duo PRhyme, together with Royce da 5'9".
