Slaine began rapping at age 9, and after moving to New York as a young man, began recording while managing night clubs to make ends meet. Slaine hooked up with hip hop legend MC Shan, and through a chance recording session at the Lordz of Brooklyn studio, was introduced to Danny Boy O'Connor of House of Pain.
That introduction led to a production deal with DJ Lethal of House of Pain, which in turn led to the mix tape release ‘The White Man is the Devil: Volume 1’ and the formation of the group Special Teamz. After the release of their self titled street cd, and a tour of Europe, Slaine joined hip hop super group La Coka Nostra, along with Ill Bill, Everlast, Danny Boy, and DJ Lethal. After problems with his planned first record, A World With No Skies, Slaine got back in the studio and recorded almost an entire new record, aptly titled A World With No Skies 2.0, which was released on August 16, 2011 on Suburban Noize Records. Slaine also released the mixtape State of Grace on August 2, 2011 in promotion of A World With No Skies 2.0. The mixtape featured songs that had been dropped from the original A World With No Skies as well as new songs produced by Statik Selektah.
In an emotional interview on Conspiracy Worldwide Radio, Slaine discussed his possible retirement from music, citing the problems he had with the planned release of A World With No Skies and the issues he has with the music industry. Slaine stated that he is likely to focus on his group efforts in 2012, potentially releasing both another La Coka Nostra and Special Teamz album.
