Spiritus Winds return to Trinity Lutheran Church in Lynnwood for a free performance featuring Scandinavian composer Carl Nielsen’s wind quintet, called by one expert “the subtlest and finest ever written,” and American composer David Maslanka’s third quintet for winds, which incorporates three chorales by Johann Sebastian Bach. The program opens with a delightful quartet by Eugène Bozza and the enchanting Danza de mediodía by Mexican composer Arturo Márquez.
