M.O.P. is an American hip hop duo composed of East Coast rappers Billy Danze and Lil' Fame. After years of underground performance, they gained 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. He has also worked for other artists including Kool G Rap and Wu-Tang Clan.
