While science tries to find the gene for art, Francine Seders Gallery displays the evidence: an exhibition of three families of artists from around the way. Late painter Michael Dailey's smoky, atmospheric landscapes are paired with his daughter Susanne's narrative woodblock prints (also paired in a great but easily missed 2009 show at Gallery 110). "Cooperative work"—this should be fun—comes from mythic abstraction titan Michael Spafford and his son, photographer Spike Mafford. And Fred Birchman, an artist who feels like an inventor, shows alongside sons Sam and Julian. Inspect all for embedded family drama.
