As the season shifts from Epiphany to Lent—and Ohio’s winter lingers—organist Rees Taylor Roberts offers Chiaroscuro, a concert meditating on the interplay of light and shadow. The program features works by canonic composers like Bach, Messiaen, Buxtehude, and Demessieux, alongside music of living composers Richard Webster and Kristina Arakelyan, and the late Akron-based composer Stephen Griebling.
