Last night, a couple of weeks after its downstairs opened, Andrew W.K.’s club Santos’ (a.k.a. Santa’s) Party House christened its upstairs space with a dance-tacular Body and Soul party. After sweating it out, we can say that Manhattan hipsters tired of schlepping out to Studio B for good D.J.'s will find a more than worthy replacement here — the room’s just a smidge smaller, but similarly minimal and airy, with two bars, black walls and ceilings, dark wood floors, and tall columns that are perfect for humping while you’re on Ecstasy. Though not yet fully installed, the sound system promises to do the cabaret license justice, with no less than sixteen five-cone speakers running the perimeter of the room. Do not come here unless you plan to dance — seating is almost nil.

We got late word yesterday that Andrew W.K.’s club Santa’s Party House a.k.a. 100 Lafayette a.k.a. (and ultimately named) Santos’ Party House was soft-opening with a party featuring D.J.'s Lee Douglas, Alex from Tokyo, and Spun. We won’t share whatever video footage we may have taken because as you can see here, absolutely no photography is allowed, but know this: Though the downstairs isn’t quite as spacious as we had imagined it after three years of construction (décor equals disco balls), it’s a long overdue throwback to the days of bare-bones box clubs (think Shelter at Hubert Street), and a godsend for anyone who has ever danced in the basement of 205 thinking the experience could benefit from a little more space and a much sicker sound system. Drinks at the basic bar were $8. D.J.'s casing the joint last night included Prince Language, Tommie Sunshine, and A Touch of Class— expect the nightly lineup to follow suit. The upstairs, according to A.W.K. himself, is opening soon — till then it’s time to shut up and dance.
