Israeli Arabs have also branched out into other musical styles. Palestinian hip-hop artist Tamer Nafar, founder of the rap group DAM, became an independent rap star after a politically charged dispute with Israeli rapper Subliminal. His music expresses the frustration and alienation that many Israeli-Palestinians feel. The rock music of Basam Beromi, singer of the group "Khalas" (Enough!), protests against the strictures of traditional Arab society. The song "What have we come to?", for example, tells the story of a young girl in love, whose family murders her for violating strict traditional codes of courtship. London-trained guitarist Michel Sajrawy combines jazz, rock, and gypsy with classical Arab music.
