Brothers Eli Hansen, a glassblower, and Oscar Tuazon, a conceptual artist preoccupied with makeshift architecture, have sprung into view over the last year. In 2007, Tuazon won the Betty Bowen Award and Seattle Art Museum collected their glass-and-wood sculpture Crystal Math; now they have concurrent shows at SAM and Howard House. The noon talk at the gallery is intimate and free. (Howard House, 604 Second Ave, 256-6399. Noon, free.) JEN GRAVES
