Roc Marciano started his career in 1999 when he joined the Flipmode Squad and made his first appearances on “Whatcha Come Around Here For” and “The Heist". Marciano left in 2001 to form the U.N., a hardcore underground hip hop group consisting of three other MCs (Dino Brave, Laku & deceased member Mic Raw) with whom he released an album on Carson Daly's 456 Entertainment in 2004. Roc Marciano appeared on the 2005 Wu-Tang Clan compilation album, Wu-Tang Meets the Indie Culture, and in Pete Rock's 2008 album, NY's Finest, drawing acclaim for such performances. Since 2008, Roc Marciano has been working on his solo career, and to widespread internet acclaim, released his entirely self-produced debut album, Marcberg on May 4, 2010 to critical acclaim.
