Right now on WPRB we’re listening to the gorgeous “Mass for the 500th Anniversary of the Death of Joan of Arc,” by Paul Paray.

Shortly after 9:00 this morning, we’ll be joined by composer Richard Einhorn. Einhorn’s oratorio, “Voices of Light,” will be performed tonight as part of a multimedia presentation, which will include a screening of the Carl Theodor Dreyer classic “The Passion of Joan of Arc” at Princeton University Chapel at 8:30 p.m. Soloists of Notre Dame Vocale and the Princeton Festival Chorus will join the Princeton Symphony Orchestra, beginning at 8:30 p.m.

Einhorn will give a free pre-performance talk at the Princeton Garden Theatre at 5 p.m. It’s all part of this year’s Princeton Festival. The Princeton Festival continues through June 26, with opera, jazz, musical theater, dance, choral, chamber and instrumental music. To learn more about it, visit princetonfestival.org.

During this morning’s visit to the WPRB studios, Einhorn will talk with us about his work on “Voices,” which has been performed over 100 times, recorded for the Sony Classical label by Anonymous 4, and issued as a bonus soundtrack on The Criterion Collection’s DVD release of the film. We’ll hear selections from the piece and sample from some of the composer’s other works.

Then at 11:00, our featured highlight will be Norman Dello Joio’s “The Triumph of Saint Joan.” It’s all music related to the Maid of Orleans this morning until 11 EDT on WPRB 103.3 FM and at wprb.com.
