The vocal ensemble Harmonia, led by Robert Pacillo, is stretching its wings with a performance with the Ars Nova Musicians Chamber Orchestra, led by artistic director Marylouise Nanna, and the St. Joseph Cathedral Choir, directed by Timothy Socha.

The concert’s centerpiece will be “Lux Aeterna” (“Eternal Light”) by the mystic American composer Morten Lauridsen. Lauridsen, who received the National Medal of Arts in 2007, is known for his transcendent, ethereal music that seeks to explore the spiritual. Listeners often say his music moves them to tears. Lauridsen’s creations also reflect the serenity of untouched nature. Before turning to composition full time, he was a forest ranger in the Pacific Northwest.

Performing together and separately, the ensembles will round out the concert with music from the Renaissance to the modern day. – Mary Kunz Goldman
