In “Domine Deus, Rex Caelestis,” our sweet-toned soprano soloist, Kiera Duffy, wove magically in and out of the soft choral fabric even though she had enough power to be heard over heavier textures, too.
“Domini Fili Unigenite” took us briefly back to the opening ebullience, before the ethereal “Domine Deus, Agnus Dei” delivered what I hear as the composer’s mystical vision of heaven. Duffy did her sweetest, most profound singing here, spiraling repeatedly up into the vocal stratosphere with effortless ease and tonal beauty.

My favorites included Kiera Duffy (heard in Opera Company of Philadelphia’s Italian Girl in Algiers last fall), who carries herself with magnetic poise and intelligence, and surpasses herself in an aria from Handel’s Alcina with great feats of vocal color. (Review of film “The Audition,” documentary on 2007 Metropolitan Opera National Council Auditions.)
