Artist Tobi Kahn is obsessed with memories of the Holocaust. His abstract landscapes depict recollections of a haunted time and place he never experienced. Simple shapes conjure rivers and roads that snake through still valleys, serene at first glance, disturbing upon reflection. Mountain peaks thrust from brooding waters, in a palette of muted browns, golds and blues. Almost always, the paintings are devoid of people. "Sky and water always stay the same," Kahn says, "no matter how well- or ill-behaved we are."
