Last week Gallery Bar, the Lower East Side hangout and art venue that is part-owned by Miami collector scion Darren Rubell, was shut down in a dramatic police raid after alleged underage-drinking and overcrowding violations. Now, however, the bar is back in business, and will be hosting a closing party tonight for “The Beautiful Chaos: A Style Installation,” a show of comic-book-inspired collages and installations by Damon Johnson (the step-son of art PR guru Nadine Johnson). Working in a self-proclaimed “urban surrealist” style, Johnson has done murals at the U.S. Open and at the Montauk Surf Lodge, and appeared in a Half Gallery show curated by Jesus author James Frey.
