With all the talk about edgy Phoenix, we forget that some of the Valley's strongest art roots are, in fact, in Scottsdale ? and we're not talking howling coyotes here. Try those equally iconic gussied-up Weimaraners, since William Wegman is a longtime member of Lisa Sette's posse. Sette is one of the most elegant women in town, with a gallery to match ? whether with a recent group exhibition focusing on hair or the amazing show that celebrated her 20 years in Scottsdale. She challenges and tempts us, and we're grateful.
