Wow, Output has been open a full year? Time keeps on slippin' into the future, as somebody once said. The Williamsburg club has spent the past 12 months bringing in an array of top-tier house and techno artists, and tonight's party is no different: The main room features Anstascia and Vivie-Ann—otherwise known as Blond:ish, the deep-house duo that records for such mighty labels as Kompakt and Get Physical—along with Philipp Jung, from Get Physical's world-conquering M.A.N.D.Y. duo. But you may want to spend your night in the Panther Room with Frank & Tony, the pairing of electronic-house mavens Anthony Collins (from Freak n' Chic and, once again, Get Physical) and NYC's own Francis "Adultnapper" Harris, the maestro of the Scissor and Thread imprint.
