It has been 13 years since Ras Kass, Canibus, Kurupt and Killah Priest first appeared together as The 4 Horsemen. "Horsementality" was featured on Canibus' 2000 B.C. album and talk of a full length project between the east and west coast emcees began. A promo video from the foursome says the Biblical-themed project will drop this summer.
Over the years the individual member continued to work together and kept the possibility of an album at arms reached. The group name was changed to simply HRSMN to allow the group to expand. Countless emcees have been rumored to be joining, including but limited to Pharoahe Monch, Keith Murray, Kool G. Rap, Crooked I, Royce Da 5'9, Rakim, Common, Vinnie Paz, Journalist, Pacewon, Young Zee, Danja Mowf, Pak Man and Lonnie B.
While an Internet only album was released in 2003 (a rare thing at the time), The Horsemen Project was cobbled together and wasn't the legitimate debut of the supergroup. In late December the group dropped a new track and confirmed they were indeed working on an album, which would feature a collaboration with fellow supergroup Slaughterhouse.
