The nation's top beatboxers are converging Friday in New Jersey to show off their skills at the American Beatbox Championships, which are taking place in Atlantic City over Labor Day weekend. And thanks to a newly added contest for international competitors, this year's battle has global repercussions. Kaila Mullady of New York City is a two-time winner of the Beatbox Battle World Championship, and a member of the group Freestyle Love Supreme. She also co-hosts and produces the American Beatbox Championship, and recently spoke about the competition with WNYC's Morning Edition host Michael Hill.
