Though there’s not much going on as far as new shows today, there is one event you should have on your radar: the Beethoven/Mozart/Wagner concert at the Gaillard. It’s Emmanuel Villaume’s final concert as Spoleto’s music director for opera and orchestra. You’ll hear Beethoven’s Symphony No. 8, Mozart’s Symphony No. 35, and Wagner’s Siegfried Idyll. The show starts at 7:30 p.m., and tickets are $10-$65.
