La Coka Nostra is an American hip hop supergroup currently composed of Danny Boy, Slaine, DJ Lethal, and Ill Bill. In 2004, its creation started when Danny Boy brought two young artists, Slaine and Big Left, to meet DJ Lethal, the DJ from his former group House of Pain. They decided to make a group, whose name came about when O'Connor teased other members with that nickname after they had a night out. They started releasing music on MySpace, and went viral.
