Boris Coelman, De Sluwe Vos, Merel Helderman

Shelter's main room on Overhoeksplein stacks three names this Friday: Merel Helderman opens at 11, De Sluwe Vos — the Patron Records founder with a reputation for relentless, house-breakbeat-rave sets — holds 1am to 6am, and Boris Coelman closes it out. A second room runs Cule and Lo Ds the same hours. Door's usually backed up, it's 18+, and nobody's in before one.
