This weekend, Halloween parties don’t get bigger than Calvin Harris’s gig at Pier 94 tonight. Go there if you’re into large crowds and larger hooks (the guy did produce “We Found Love,” “Feel So Close,” and “Sweet Nothing”). Ticket prices, however, are equally outsized, so if you’re looking to save some money to invest in your costume, there’s plenty happening downtown and in Brooklyn. For starters, the Rub is bringing up Philly’s Bo Bliz—he of the legendary White Tees White Belts party—for their annual Halloween soirée, while Mister Saturday Night residents Eamon Harkin and Justin Carter keep it in-house, so to speak, but promise to turn venue 12-turn-13 into an underwater paradise. Meanwhile, at a location not yet disclosed, Hercules and Love Affair reform to keep you dancing until long after the makeup has begun to wear off.
