Biz Markie is an East Coast hip hop artist, DJ and world-renowned Human Beat Boxer, best known for humorous singles like "Just a Friend" and "Pickin' Boogers." and his pre-MTV hit "Vapors". He has been labeled The Clown Prince of Hip-Hop. His career began in the 1980s. In 1992, Biz recorded a song called "Alone Again," but Gilbert O'Sullivan claimed the track featured an unauthorized sample of his hit "Alone Again (Naturally)," and served Biz papers. His career was quite damaged from the lawsuit, and Biz ducked out of the harshest glare of the limelight for the remainder of the 1990s.
