U.N. was a Harlem-based hip hop group founded by Cam'ron in 2009. The group came to formation after Cam'ron had a falling-out with fellow Harlem rapper and co-founder of the Diplomats Jim Jones in 2007.
Vado released a mixtape titled "Boss of All Bosse," on August 12, 2009, followed by a second mixtape called, "Boss of All Bosses 2," on January 12, 2010. Both mixtapes were released under the U.N. banner. After this, the U.N. released Boss of All Bosses 2.5, an expansion of the first two original mixtapes, released on May 12, 2010. Cam'ron and Vado have since announced future plans for a solo Vado mixtape and album, as well as a U.N. album distributed by Asylum.
