Beastie Boys is an American hip hop band from New York City, formed in 1979. 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 1979 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. The group sold 22 million albums in the United States and 40 million albums worldwide, making them, according to Billboard, "the biggest-selling rap group" since 1991. With seven platinum or better albums from 1986-2004, the Beastie Boys were one of the longest-lived hip hop acts worldwide, and they continued to enjoy commercial and critical success more than 25 years after Licensed to Ill. In 2009, the group released digitally remastered deluxe editions of their albums Paul's Boutique, Check Your Head, Ill Communication and Hello Nasty. Their eighth studio album, Hot Sauce Committee Part Two, was released in 2011, and received positive reviews. They were inducted into the Rock and Roll Hall of Fame in April 2012, "just the third rap group to enter the Hall, after Run-D.M.C. (2009) and Grandmaster Flash and the Furious Five (2007)." The following month, MCA died of cancer of the parotid salivary gland, which led to the speculation that the other members may decide to disband the group.
