Jamal Bush (born November 4, 1975), better known by his stage name Rock (or Big Rock, or alternatively The Rockness Monstah), is an Americanrapper, famous as a member of hip hop collective Boot Camp Clik and the duo Heltah Skeltah along with Sean Price. He is known for his deep, grimy voice and having a sophisticated and rugged flow.
After releasing two albums with Heltah Skeltah, Nocturnal and Magnum Force, Rock left Duck Down Records and pursued a solo career. He signed to DJ Lethal's Lethal Records and recorded a solo album titled Planet Rock, which was never released after the label folded. He didn't make an appearance on the Clik's 2002 group album The Chosen Few, being the only member of the "Great 8" not to appear.
Rock has admitted being an 80's BrooklynDecepticons gang member, along with fellow Heltah Skeltah group-member Sean Price and Onyx rapper Sticky Fingaz. On January 15, 2008, Rock was arrested for an assault and attempted murder charge after he allegedly gunned down a rival while working as a pimp. He was released on a $125,000 bail about a week later on January 24, 2008. Court reports show Rock's manager Ben Aubin of BAM posted bond for the rapper's release. Mr. Aubin has categorically denied any confirmation of his client moonlighting as a pimp.
The legal trouble seems not to have affected his career as a rapper, as Heltah Skeltah returned to the studio to record their third album, D.I.R.T., which was released on September 30, 2008.
