“Fine choral singing was a hallmark of this [American Guild of Organists National] Convention, and the finest that Chicago had to offer was presented on Thursday morning by Chicago a cappella in St. Clement Church. Just when I thought one more straight-tone choir would make my head burst, this professional group of nine singers arrived to show how color, emotion, and expression need not be sacrificed for blending and intonation. They performed without a conductor, yet displayed breathtaking ensemble and control. The expressive use of vibrato by soloists was a lesson in stylistic elegance....every piece was approached with a unique choral color. Chicago a cappella is a jewel in the crown of Chicago's musical life.”
