For over 20 years, Armand Van Helden has been on the cutting of dance music, both breaking down walls between genres and accidentally opening up new ones in the process. Sitting on a beach in Miami a few days after the close of Ultra, our conversation briefly interrupted when a woman decided he would be a good person to ask for weed, the DJ selected and spoke about 15 of his most essential tracks, a list that includes everything from New York house classics like "Witch Doktor" and remixes for Tori Amos and Daft Punk to a couple of the tunes he and A-Trak released as Duck Sauce on last week's Quack LP. By Nick Murray
