Concert Hall Curveballs are those little disasters that happen in public and are embarrassing but normally not fatal — an exploding violin, for example. The group Florilegium recovers from its curveball and plays some Bolivian Baroque, an anonymous sonata from the Jesuit missions in the Chiquita region of Bolivia. Then we move on to Indianapolis to hear the gold-medal winner of the International Violin Competition. Augustin Hadelich joins pianist Roland de Silva in the final movement of Beethoven's Violin Sonata No. 1. And a tip of the hat to a newly minted genius, as the MacArthur Foundation announces its "genius awards."
