Beyond the jangle of jingling bells, below the heaps of seasonal schmaltz, there is another kind of holiday music: Powerful and mysterious, it calls on listeners to reflect on the "Meaning of the Season" in ways no canned carol can inspire. Benjamin Britten's Saint Nicolas might be the best of this rarified genre. This cantata for tenor soloist, chorus, children's choir and orchestra recounts the legendary adventures of the Turkish bishop who, through quirks of fate and history, would eventually become known to millions as "Santa Claus." If your knowledge of Santa stops at reindeer and elves, prepare yourself for an exotic tale of a wonder-worker who, among many other miracles, resurrected three boys who had been pickled by a cannibalistic butcher. Houston Chamber Choir, along with The Treble Choir of Houston, present St. Nicolas at South Main Baptist Church.
