Marriage of Figaro (in Italian with surtitles), January 10, 7:30
La Traviata (opera in concert), February 15, 3:00
Kathleen Battle (spiritual and sacred songs recital), March 21, 7:30
Cinderella (in English), April 5, 3:00
Subscription prices are great: from $84 to $161 for all four operas. ($21 an opera! That's cheaper than the Galaxy!) Subscriptions are on sale now and per-performance tickets go on sale December 1. The box office number is 519/578-1570 or 800/265-8977.
