Ill Bill is an American rapper and producer from Brooklyn, New York, and the brother of Necro. Born William Braunstein, Ill Bill cofounded the death metal band Injustice in 1988, with Ill Bill. The band disbanded two years later, and the brothers soon began careers as rappers, maintaining a strong heavy metal influence in their music. In 1995, Ill Bill formed Non Phixion, which secured a major label death with Geffen Records through 3rd Bass member MC Serch. However, the group did not release any albums until Ill Bill formed Uncle Howie Records in 1998. The label was named for Ill Bill's uncle, Howie Tenebaum, a former drug addict. In 2006, Ill Bill joined La Coka Nostra, comprised of former House of Pain members Danny Boy, Everlast and DJ Lethal, and Slaine. La Coka Nostra is signed to Suburban Noize Records.
