What is a zarzuela? Glad you asked. It's a form of Spanish opera that got its start in the mid-1600s and is usually short and comic. Director Salomé Martínez-Lutz and conductor/pianist Pablo Zinger have put together a showcase of this classical music genre that features a variety of zarzuela music consisting of archetypal Spanish beats as well as Afro-Caribbean rhythms. Perhaps best of all, special seating will be available to enjoy a glass of wine during the performances at the National Hispanic Cultural Center (1707 Fourth Street SW) this Saturday, July 29, at 8 p.m. and Sunday at 3 p.m. The show is produced by Teatro Nuevo México. Tickets are $10 to $25, available in person at the NHCC box office, or through Ticketmaster at 883-7800 or ticketmaster.com. For more information, call 724-4771.
