For 10 to 12 weeks every year, Wolf Trap Opera is the summer home of dozens of artists representing the best of the next generation of singers. This year, 32 have been chosen from more than 1,200. Famous alumni include Denyce Graves, Lawrence Brownlee and Christine Goerke. Since 1971, the Wolf Trap Opera program has been thrilling audiences with innovative programming, and this year's season is more expansive than ever. The summer season features two operas by Philip Glass (celebrating his 80th birthday year), two company premieres (Puccini's Tosca and Rossini's The Touchstone), a kiddie opera about musical wombats, and "Untrapped," which brings WTO artists into the greater community. Wolf Trap Opera director Kim Pensinger Witman discusses this expanded operatic season as also speaks about the thriving classical music scene and how today's singers have changed in the past 46 years of WTO's history.
