Beastie Boys
The Beastie Boys were an American hip hop group from New York City formed in 1981. The group comprised Michael "Mike D" Diamond (vocals, drums), Adam "MCA" Yauch (vocals, bass) and Adam "Ad-Rock" Horovitz (vocals, guitar).
The Beastie Boys were formed as a four-piece hardcore punk band, the Young Aborigines, in 1979 by Mike D (vocals), MCA (bass), John Berry (guitar) and Kate Schellenbach
Young Aborigines. In 1981, Adam Yauch, aka MCA, a friend and follower of the band, became their bass player, and on the suggestion of their then-guitar player, John Berry, the band changed their name to the Beastie Boys. By 1983, Adam Horovitz (Ad-Rock) joined, and their sound began to shift away from punk to hip hop.
In 1992, Diamond founded the Beastie Boys' now-defunct record label Grand Royal Records. He is also interested in interior decoration
