1 is the debut studio album by Harlem hip hop duo U.N., which is composed of Cam'ron and Vado.

[1] The album features guest appearances from Young Chris, Gucci Mane and Felony Fame.

David Jeffries of AllMusic gave album three and a half stars out of five, saying "This ridiculous kind of irresponsibility is the reason fans signed up in the first place, and when it’s delivered with a scrappy, fresh, sometimes even silly set of beats on the level of Cam’s 2009 album Crime Pays, all the better.

Small complaints include Vado getting lost in the shuffle and the intro's dramatic promises of a “revolution” when everything else is an obvious return to form.

"[2] The album debuted at number 133 on the Billboard 200 chart, with first-week sales of 3,700 copies in the United States.
