Duval Clear, known better by his stage name Masta Ace, is an American rapper and record producer from New York City. He appeared on the classic 1988 Juice Crew posse cut "The Symphony". He is noted for his distinct voice and rapping proficiency, and has influenced several MCs.

The Juice Crew was an American hip hop collective made up largely of Queensbridge, New York–based artists in the mid-to-late 1980s. Founded by radio DJ Mr. Magic, and housed by Tyrone Williams' record label Cold Chillin' Records, the Juice Crew helped introduce New School artists MC Shan, Big Daddy Kane, Biz Markie, Roxanne Shante, Masta Ace, Tragedy, Craig G and Kool G Rap. The crew produced many answer records and engaged with numerous "beefs" – primarily with rival radio jock Kool DJ Red Alert and the South Bronx's Boogie Down Productions, as well as the "posse cut", "The Symphony".
