Because it's fun to drink at the museum and see art at night. Because the new show Adaptation is new. Because the oldish show Richard Misrach: On the Beach is all photographs taken from a single hotel balcony in Hawaii. Because Liz Magor's reverse taxidermy is down in the basement waiting for you. Because there's music by a DJ who bothered to name himself "Freddy, King of Pants." (Henry Art Gallery, 4100 15th Ave NE, 543-2280. 8–11 pm, $10.)
