Beastie Boys is an American rap/rock band from New York City, formed in 1981. For the majority of its career, the group has consisted of three MCs and musicians Michael 'Mike D' Diamond (vocals, drums), Adam 'MCA' Yauch (vocals, bass) and Adam 'Ad-Rock' Horovitz (vocals, guitar). Originally formed as a four-piece hardcore punk band in 1981 by Michael Diamond (vocals), John Berry (guitar), Adam Yauch (bass) and Kate Schellenbach (drums), the band appeared on the compilation cassette New York Thrash, before recording their first EP Polly Wog Stew, in 1982. After achieving moderate local success with the 1983 experimental hip hop 12-inch 'Cooky Puss', the group transitioned to hip hop in 1984 and released a string of successful 12-inch singles. The Beastie Boys toured with Madonna in 1985 and a year later released their debut album Licensed to Ill.
