Danger Mouse's The Grey Album is considered a landmark in rock/hip-hop fusion, which featured a "mashing" together of vocals from Jay-Z's The Black Album with beats created from The Beatles' White Album. The project, although met with a cease-and-desist order from EMI, pushed the producer into the international spotlight.
He has since embarked on a series of notable collaborations, working with rappers such as Gemini and underground superstar MF Doom, and finding platinum-selling success with Gnarls Barkley and Gorillaz (producing the latter's second album, Demon Dayz).
