The San Francisco Choral Artists are doing their best, in their Christmas program, to capture both extremes of the Christmas season -- the Saturnalia-inspired, feasting, egg nog-drinking, shopping, sleigh-bells-in-the-snow side, and the religious, contemplative, midnight mass, quiet-evening-by-the-fire side.
If you're one of those people who wants it all, there are two more performances left of this holiday concert, which includes a lot of 21st-century music, as always with this adventurous group.
