You can’t miss the towering red neon sign atop the Bendix Building. Once and partly still a bustling garment industry center of manufacture and merchandising, increasingly, it’s also home to a dance company (Heidi Duckler), artist studios (about 40) and independent contemporary art galleries (about 10 at last count). And this weekend, that number ticks up, with the inaugural exhibition at Von Lintel Gallery anchoring a night of opening receptions throughout the building.
