Gnarls Barkley is the experimental hip-hop and soul duo consisting of producer Danger Mouse and singer CeeLo Green, known for their innovative blend of genres and darkly playful aesthetic. Rising to prominence with their 2006 debut album "The Odd Couple" and the viral hit "Crazy," the group became celebrated for pushing creative boundaries and defying genre conventions. Though the project has been largely dormant since their 2008 follow-up "The Odd Couple: By Design," Gnarls Barkley remains an iconic influence on alternative music and experimental production.
