House on Wax brings a vinyl-minded house session to MAD Radio, the Williamsburg listening bar built around a high-fidelity sound system. Markciano, a long-running fixture of New York's underground, and LemAr trade deep, groovy, disco-tinged house records across the night. Entry is free, with an early happy hour from 6 to 9 PM, and RSVPs are available through Shotgun.
