Premise: Beastie Boys . Originally formed as a four-piece hardcore punk band , the Young Aborigines , in 1978 by Diamond ( vocals ) , John Berry ( guitar ) , 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 '' , Schellenbach dropped out and the Beastie Boys made a full transition to hip hop , releasing a string of successful singles .
Hypothesis: Beastie Boys changed genres.
