Tomorrow morning on WPRB, I’ll have a very special guest in composer Richard Einhorn. Einhorn’s oratorio, “Voices of Light,” will be performed tomorrow night, to accompany a screening of the 1928 classic film, “The Passion of Joan of Arc,” that inspired it.

Performers will include soloists of Notre Dame Vocale, the Princeton Festival Chorus, and the Princeton Symphony Orchestra. This extraordinary event, the result of a partnership between the Princeton Symphony, the Princeton Garden Theatre, and The Princeton Festival, will take place at Princeton University Chapel at 8:30 p.m. Einhorn will give a free pre-performance talk at the Garden Theatre at 5 p.m. For more information, visit princetonfestival.org.

We’ll do everything we can to set the mood for this special presentation of Carl Theodor Dreyer’s magnum opus – which sports a riveting performance by actress Renée Jeanne Falconetti – with a special on-air visit from the composer at 9 a.m. tomorrow. Einhorn will talk 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 oratorio, as well as sample some of the composer’s other music.

For the remainder of the morning, we’ll honor Joan of Arc with music written to her memory, music inspired by the Hundred Years’ War, music evocative of the Middle Ages in general, and some authentic music of the period.

We get medieval, tomorrow morning from 6 to 11 EDT, on WPRB 103.3 FM and at wprb.com. The stake is always well done, on Classic Ross Amico.
