If you’re anything like us, your opera voice is usually reserved for the shower. Not so for Barbara Caprilli and Rob Glaubitz, assistant professors of voice at the University of Central Oklahoma School of Music. See them perform separate one-act, one-man operas “Bon Appetit” and “A Water Bird Talk” 7:30 p.m. Tuesday at the UCO Jazz Lab, 100 E. Fifth St. in Edmond. Tickets are $10.
