Jamal Bush (born November 4, 1975), better known by his stage name Big Rock, or alternatively The Rockness Monstah, is an American rapper, famous as a member of hip hop collective Boot Camp Clik and the duo Heltah Skeltah along with Ruck. 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. He made his official return to Duck Down in 2005, making appearances on Sean Price's Monkey Barz album and Smif-N-Wessun's Smif 'N' Wessun: Reloaded album. He's performed songs for a variety of video games including "I Am Rock" for Need for Speed: Most Wanted, "This Is Me" for Blitz The League II and "I Am Rock" for NFL Street 2. He and the Boot Camp released their third group album, The Last Stand, on July 18, 2006. 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.
