About the party

Groovelab presents a Halloween afterhours with Boris at Polygon on Vandervoort Avenue in Brooklyn. Doors open at 4 AM on Sunday, Nov 1, so it belongs to Saturday night, Oct 31, running into the early hours of Sunday and on until noon. The promoter describes Boris as one of the pioneers of the New York underground.

What to expect

This is a pure afterhours: the listing is brief and describes no theme, costume guidance or production. My take: for people who want to keep dancing after their Halloween night ends elsewhere and hear Boris through Sunday morning.
