About the Chorus

Colla Voce Seattle is a mixed-voice ensemble with singers drawn from all around the Seattle area. Dedicated to presenting concerts exploring a wide range of choral literature, Colla Voce offers singers the opportunity to learn and perform a variety of serious repertoire including 19th-century spirituals, psalms, and plainchant, as well as works by 20th and 21st century composers. Much of this repertoire is a cappella, drawing from the traditional choral library as well as serious literature from lesser-known choral composers.

Conducted by Mark Adrian, the ensemble numbers between 20-25 singers from all walks of life. Concerts are typically performed at St. Catherine of Siena in the Maple Leaf neighborhood of north Seattle, and at Benaroya Hall in downtown Seattle.


Mark Adrian, Artistic Director and Conductor, earned his BA in Music from the University of Washington, studying with renowned conductors Abraham Kaplan, Geoffrey Boers and Peter Erös. He has since gone on the complete graduate coursework for the Doctor of Musical Arts degree, specializing in choral conducting.
