You have two strong reasons to go to this show: James Lavadour is the J.M.W. Turner of the Northwest, a maker of landscape paintings that are layered and gauzy and vivid, full of weather and invitation. He's a member of the Umatilla Tribe, and his relationship with the land was, and continues to be, his school of art, but these surfaces reveal influences from pop artist Robert Rauschenberg to Chinese painting. Your second reason to go? Grover/Thurston is moving. Say good-bye to the gorgeous, double-height old Occidental Square space the gallery has been in since 1993. Starting in August, Grover/Thurston will be housed in the squat nearby space that Catherine Person Gallery recently vacated. In this economy, mixed news is good news.
