The most accomplished choristers of Oakland, California's highly-regarded Pacific Boychoir Academy are the Troubadors, who join with The Pacific Collegium, a professional chamber ensemble that combines exceptional vocalists and instrumentalists, to perform three of Benjamin Britten's favorite Christmas pieces. The dramatic, powerful 12-part "A Ceremony of Carols" was written in the middle of WWII, the simple and fetching "Hymn to the Virgin" has been a Christmas favorite since he wrote it while ill in bed at age 16; and the 7-part "A Boy Was Born," was a student exercise by Britten published in 1934 that deals with the nature of innocence and childhood in the Nativity story. Led by director Kevin Fox, the Troubadors handle this eclectic, often difficult material beautifully, and the Collegium, directed by Christopher Kula, adds strong instrumentals and vocals to the mix. This is a lovely, very different kind of Christmas collection of pieces by a master composer.
