The Chalice Consort brought its remarkable sound and splendid musicianship to St. Monica Catholic Church in San Francisco Saturday night, in an a cappella concert ably led by Matthew Walsh. The first half of the program was beautifully constructed, starting with unison chant, continuing with a confluence of chants, then alternating chant with solo ensembles, and finally singing in full four-part and six-part harmony. The subject: the birth of Jesus and the ensuing Epiphany, when the Magi come on their pilgrimage.
In the live acoustic of the St. Monica sanctuary, the eight women's pure, strong, focused voices carried wonderfully, unimpaired by any excess of vibrato. They led off with an Ambrosian chant, Videntes stellam Magi (The wise men seeing the star), which wove together the story of the Magi with elements of Mary's Magnificat and the Gloria from the Mass.
The eight men followed with an anonymous Medieval double motet in three parts, each with its own text, two of them about the Magi and one telling the Christmas story of the angels appearing to shepherds. Epiphaniam Domino (The epiphany of our Lord), a 15th-century sequence by Guillaume Dufay, alternated chants and solo ensembles. The unison chants, some sung by the women and some by the men, led into chant-based trios sung by solo voices in various combinations.
The full chorus continued with an electrifying performance of a 16th-century polyphonic motet. Reges Tharsis (The kings of Tharsis), by John Sheppard, took the sopranos up to stratospheric heights — a striking contrast with other Medieval and Renaissance repertoire — and the Chalice sopranos nailed it. Magi veniunt ab oriente (The wise men came from the East) by Clemens non Papa, and yet another Videntes stellam by Orlandus Lassus, also told the Epiphany story. In one of many marvelous moments, the chorus, in the Lassus motet, sang a suddenly hushed "they fell down and worshipped Him" ("procidentes adoraverunt eum").
A felicitous telling of the Birth story ended the first half of the program: Palestrina's A solis ortus cardine (From the rising of the sun). This was Palestrina at his best, alternating unison chants with four-part harmony, peaking to a superb five-part chorus on "gaudet chorus coelestrum" (The heavenly chorus rejoices) and culminating in a full-unison chant of the Gloria. The Chalice Consort was heavenly indeed, singing with perfect intonation and beautifully balanced sound.
