RBL Posse (short for Ruthless By Law) was a rap group from the Hunters Point district of San Francisco, California. A Bay Area rap duo formed at the beginning of the 1990s by its original members, Black C (Christopher Matthews) and Mr. Cee (Hubert Church). The pair began producing tracks at Black C's studio and emerged in 1991 with the underground hit "Don't Give Me No Bammer". Thanks solely to their own independent distribution through In-A-Minute Records, RBL sold almost half a million copies of their first two albums, "A Lesson to Be Learned" (1992) and "Ruthless By Law" (1994).
