Two touring youth choirs from Saint Mark’s Cathedral in Seattle will be the featured performers at the Choral Evensong service — evening prayer or vespers set to song — at Saint David’s Episcopal Church, Saturday, April 20, beginning at 5:30 p.m.

The choirs will also join in the St. David’s morning worship service, at 9:30 a.m., on Sunday.

Saint Mark’s Choir School is a member of the Royal School of Church Music in America. The school emphasizes well-rounded musicianship as part of its program, as well as lifelong growth in music and faith, vocal and ear training, as well as theoretical knowledge, and ministry through liturgical leadership and community service for grades K-12.

The Boys and Girls Choir, directed by Rebekah Gilmore, includes children in grades 3-7. The Youth Ensemble, directed by Brian Fairbanks, features children in grades 8-12, and younger men whose voices have matured.

Both choirs sing music from a variety of traditions, from Taizé chant to gospel, to world and traditional music. The choirs sing Choral Evensong regularly at Saint Mark’s Cathedral.

Saint David’s Church is located at the intersection of Marguerite Place and Park Street, in Friday Harbor. For information, 378-5360.
