Brooklyn natives, The Upperclass Men, are an outfit that has fused rap and rock together, creating a niche of their own. The group has two rappers at the forefront who are backed by a live band. With their major hip-hop influences, this band’s style has evolved into a genre that is completely unorthodox. The Upperclass Men will be celebrating the birthday of vocalist HD Stephenson with a show at Tammany Hall in New York on May 31. Doors open at 10 p.m. and tickets are $10.
