Since 1975, Thirteen Strings Chamber Orchestra has dazzled eardrums with eclectic performances that span a scope of styles with an emphasis on Canadian repertoire. The "Illumination" concert boasts a mellifluous pairing of pieces from the baroque era and 20th century. Guest conductor Thomas Annand commences the night with works by Italian prodigy Pietro Locatelli, whose virtuosic, impassioned pieces give way to 20th-century Canadian composer Brian Cherney's quietly intense compositions.

A subsequent intermission grants patrons a chance to brush stray treble clefs out of their hair before the orchestra resumes from the church's organ loft with pieces by American symphonist Howard Hanson and Russian romantic composer Paul Juon. St. Andrews Church's soaring ceilings, gothic arches, and colourful stained glass windows provide dazzling confines in which to marinate ear drums in musical notes freshly squeezed by Thirteen String's masterful string strokers.
