The annual summertime Jersey Fresh Jam’s status as Trenton and New Jersey’s leading hip-hop festival gets a boost from the involvement of Masta Ace. As the British website Jazz Cafe says, “Brooklyn’s Masta Ace is an iconic figure within the East Coast hip-hop scene. His flows have influenced the likes of Eminem, Rakim, and Big Daddy Kane to name few, in a career that has spanned over two and a half decades.” The Trenton event held since 2005 on the grounds and walls of the Trenton company TerraCycle is set for Saturday, August 12, from noon to dusk.
