American musician and rapper Adam Yauch of the Beastie Boys has died in New York.
Yauch, who went by the stage name MCA founded the influential hip-hop group with two friends in the 1980s.
The Beastie Boys sold more than 40 million records, with hits including Fight for your Right (to Party) and No Sleep Till Brooklyn.
The BBC reports they began as a hardcore punk outfit called The Young Aborigines in 1979 but switched to hip hop in 1984.
Their debut album Licensed To Ill was issued two years later.
The Beastie Boys were inducted into the Rock and Roll Hall of Fame last month, but Yauch was not able to attend.
Yauch, 47, revealed he had cancer in July 2009.
