Join us for a special anniversary concert celebrating our 10th season!
The concert centers around the world premiere of DAWN, composed by Laura Hawley and commissioned specifically for this milestone.

Our program also features selections hand-picked by the chorus members themselves, giving you a beautiful glimpse into the heart of our choir. Prepare to be immersed in the lush, six-part a cappella arrangement of Rheinberger’s Abendlied ,  Hildegard von Bingen’s O Virtutis Sapientiae, arr. by Katerina Gimon, the iconic tones of Gordon Lightfoot’s Song For a Winter’s Night, among other treasures.

Directors as guest conductors:

• Laura Hawley (Founding Artistic Director, 2015-2018)
