Quadrivium, a professional vocal chamber ensemble, kicks off their second season with Hosanna!, a concert celebrating the power of the heavenly spirit. Selections include William Byrd's elegant Mass for Five Voices and motets by Rheinberger, Barber, Mathias, Rubbra, and Bortniansky. Participants in the Hosanna! Choral Workshop will join Quadrivium and guest conductor Thomas Heuser for the finale, Ola Gjeilo's moving hymn, The Ground.

Hosanna! features guest bass-baritone Toby Vaughn Kidd, tenor Andreas Tischhauser, and Maestro Thomas Heuser. It is supported in part by the Fort Lewis College Artist in Residence program.

Tickets available at the door, $20 or $5 with valid student ID.
