Janelle Monae.

FLATT magazine, the art world insider bible, is celebrating its fourth issue (tuxedo-wearing beauty Janelle Monae is on the cover) at the controversial, still-debaucherous LES punk burlesque club The Box. There will be a special—fully clothed—musical performance by Niia Bertino and deejay sets by rock photographer Mick Rock and the Electric Room’s favorite spinner DJ Cash, who loves to Instagram perky models with “I Heart Cash” stickers over their bare boobies, which is very The Box. The crowd will run the gamut from art stars like Ryan McGinness to the cool kids who hang out at The Hole Gallery when it’s not even open for business. And we’d be remiss if we failed to mention our own New York Artists party; that’s certainly where we’ll be.

The Box, 189 Chrystie Street, (212) 982-9301, 8pm-11pm, by invitation only; New York Observer Art Party with ArtNet, The Standard East Village Penthouse, 25 Cooper Square, 6:30pm-9:30pm, by invitation only.
