The Mercyhurst Institute for Arts & Culture opens the Christmas season with a performance by the renowned Vienna Boys Choir on Monday, Nov. 26, at 7:30 p.m. in the Mary D’Angelo Performing Arts Center. Today, there are 100 choristers between the ages of 9 and 14, divided into four touring choirs that give around 300 concerts each year, attended by almost half a million spectators around the world. On Sundays, the boys perform with members of the Vienna Philharmonic Orchestra and of the Vienna State Opera Chorus in Vienna’s Imperial Chapel, as they have done since 1498. Tickets are $30 for adults, $25 for seniors, and $20 for students/youth. To purchase tickets, visit miac.mercyhurst.edu or call the box office at 814-824-3000.
