In 1999, the Beastie Boys released an album titled “Country Mike’s Greatest Hits” as a compilation of tracks by one of their members, Michael “Mike D” Diamond. However, the album was never officially released, and it exists only as a rare bootleg recording and only originally given out for holiday presents. The album was never intended to be a serious release but rather a tongue-in-cheek project within the Beastie Boys’ discography.
