Hailing from Boston, the mid-'90s rap group
the Almighty RSO (which stands for "Rock Solid Organization") is comprised of
Deff Jeff,
E-Devious,
Tony Rhome, and
Ray Dog. After releasing an EP,
Revenge of da Badd Boyz, in 1994, they delivered their full-length debut,
Doomsday: Forever RSO, in the fall of 1996. The album became a success on the strength of the hit single "You Could Be My Boo," which featured guest vocals by hip-hop diva
Faith Evans. ~ Stephen Thomas Erlewine, All Music Guide
