Tonight is the kick-off party for Mocada‘s latest show, “The Gentrification of Brooklyn: The Pink Elephant Speaks.” The group show (including some artists who’ve been displaced by gentrification) delves into “how urban planning, eminent domain, and real estate development are affecting Brooklyn’s communities and how residents throughout the borough are responding.” The public is welcome at the opening reception tonight from 6 to 9 p.m. at 80 Hanson Place.
