Eminem is an American rapper, songwriter and record producer from Detroit, Michigan, who emerged in the late 1990s and became one of the most commercially successful and influential figures in hip hop. His music spans genres including hip hop, rap rock and elements of pop, characterized by rapid-fire, intricate rhyme schemes, vivid storytelling, dark humor and autobiographical themes addressing poverty, family conflict, addiction and fame. Eminem is known for his alter egos and theatrical persona, provocative and often controversial lyrics, and a dynamic vocal delivery that ranges from aggressive, confrontational tracks to introspective, confessional songs. His production often blends hard-hitting beats with melodic hooks and cinematic samples, and his work has had a significant impact on mainstream perceptions of rap and on the prominence of white artists in hip hop.
