The Northwest Boychoir celebrates its 40th anniversary with the presentation of its 36th season of “A Festival of Lessons & Carols,” featuring regional performances. These holiday concerts showcase the 90-member combined chorus of the Northwest Boychoir and Vocalpoint! Seattle.

Several local students are members of the Northwest Boychoir: Ben Puryear and Nathan Condon, both 12, are students at Evergreen Middle School and are members of the Northwest Boychoir. Ben’s sister, Claire Puryear, 16, is a Redmond High student and is a member of Vocalpoint! Seattle, which joins the Boychoir for these performances. Nathan’s sister, Kaitlyn Condon, 15, is an Eastlake High student and Vocalpoint! Seattle member.

Patterned after the Christmas Eve observance at King’s College in Cambridge, England, “A Festival of Lessons & Carols” has become a holiday tradition for thousands of families in the Puget Sound region. This classical performance consists of nine holiday readings, each followed by a traditional carol performed by the choir, and another carol sung by the choir and audience.
