The Tufts University Sunday Concert season presents the Tufts Wind Ensemble in a performance titled “Pax et Lux” (Peace and Light), the university’s motto, which was adopted in 1857 and inspires this program. The repertoire includes Frank Ticheli’s “Lux Perpetua” and David Maslanka’s “Hymn for World Peace.” TUWE will also present music written for Tufts College some 100 years ago. John McCann, director. Free and open to the public with no tickets required. This performance also may be viewed online through Tufts Music Live Streaming.
