The rising opera singer is seen seducing a woman in the clip, which recently premiered on his official Vevo account.
'Without A Song' is the latest cut from the 31-year-old's forthcoming debut album, which is due in early 2012.
The LP was produced and arranged by Steven Baker and Christian Seitz, and includes renditions of 'Deep River', 'Silent Night' and 'Nearer My God To Thee'.
The Harlem-born star, whose full name is Noah Stewart, previously sang backup for Mariah Carey at Madison Square Gardens and Coolio on the Late Show with David Letterman.
He will also make his stage debut next year in Madame Butterfly and Judith Weir's Miss Fortune.
