Artwork by Matthew Oates

A reminder: if you missed Tuesday’s screening of Clayton Patterson’s Tompkins Square riot footage in its 3.5-hour entirety, stop by the New Museum tonight for From the Underground and Below, a screening of several short documentaries (and an excerpt of the riot footage) by Patterson on the “art, performance, and popular struggle” of the Lower East Side.

Over in Williamsburg, it’s Every Second Friday again tomorrow, so all these galleries are staying open late, and a few others are even holding openings. Read on for our weekend art picks.

Audra Wolowiec’s “sound-sculpture hybrid” of wooden beams and embedded speakers, called “Warm Up,” will be shown in conjunction with a series of charcoal grid drawings by Alissa Blumenthal, a Russian woman who immigrated to New York in 1925 and drew this collection of grids in the ’50s. Except not really, because Blumenthal is the pseudonym of contemporary artist Tatiana Istomina, who made all that up and drew the grids herself last year.
