The Camerata di Sant'Antonio, led by conductor Christopher Weber, is warming up for its Christmas concert. While the orchestra's roots are Italian, its reach is international, and the Christmas concert is focusing on the music of Germany.

Anton Webern, not often a yuletide staple, gets his moment in the winter sun, with a performance of his "Lansammer Satz." The program also includes Max Bruch's "Serenade on Swedish Folk Tunes" and Johann Heinichen's Pastorale per la Notte di Natale for two oboes d'amore accompanied by the Camerata strings. There will also be a Christmas cantata -- "Uns ist ein Kind geboren" ("Unto Us a Child is Born") by Johann Kuhnau.

Featured performers include oboists Paul Schlossman and Christine Ford; soprano Holly Bewlay, bass Gary Sage and the choirs of St. Mary of the Cataract, Divine Mercy and the Camerata Chamber Singers.

Organizers promise mysteriously: "As always, we saved a surprise for the end and a delicious Christmas reception after the concert."

The concert takes place at 7 p.m. Sunday in St. Anthony of Padua Church (160 Court St., behind City Hall). Admission is $17 at the door. Call 854-2563.
