The In Sound from Way Out! Is an instrumental compilation by the Beastie Boys, released in 1996. The title and cover art concept were borrowed from the Perrey and Kingsley album of the same name. Beastie Boys were a hip hop group from New York City, formed in 1981. For the majority of their career, the group consisted of Michael "Mike D" Diamond (vocals, drums), Adam "MCA" Yauch (vocals, bass) and Adam "Ad-Rock" Horovitz (vocals, guitar). The Beastie Boys have sold 26 million records in the United States and 50 million records worldwide, making them, according to Billboard, the biggest-selling rap group since the magazine began recording sales data in 1991.
