If you can’t wait a whole month to get your fix of the Swedish sensation’s glossy dance floor fillers, head to the Green Lantern on Friday night for the second annual Shift party. DJs MAJR, the Pocketgays and Charlie Kordes will have a two-level party going: One floor will be nothing but Robyn, while the upper level will mix songs by Robyn and a variety of other “Sirens,” including Kylie Minogue, Little Boots, Lady Gaga and Nicki Minaj. You’ll want to get there early — it’s going to be packed — but to encourage early arrival, the Logan Circle gay bar is offering free vodka drinks from 10 to 11.
