A very bad thing happens to a man, and when he comes to the studio of video artist Meiro Koizumi to recount this bad thing in a testimonial, an even worse thing happens—to the man and to us watching. Koizumi knows the evil a camera can do, and he is not afraid to use it. You have been warned. This artist doesn't pose as a good guy. (Hedreen Gallery, 901 12th Ave, 296-2244. 1:30–6 pm, free.)
