Get ready to swap your zombie shuffle for some real moves — this Halloween, an international crew of dance teachers from Brazil and Russia are leading a Brazilian Zouk flashmob that’s equal parts spooky and spectacular. Over three days of workshops, you’ll learn the routine (no experience needed, it’s open-level), then hit the streets for a Halloween night performance across three locations, before winding down — or up — at the afterparty. Classes and rehearsals run Oct 26, 29, and 31 at Yihai Mansion in Jing’an. Costumes, beats, and a lot of undead flair included.
