The Southwest Chamber Players announce their 22nd annual Christmas concert at Saint Augustine’s Church, 555 Water St., SW, on Thursday, Dec. 20, beginning at 7 p.m. In addition to the traditional assortment of carols, this year’s edition will have a distinctly Russo-centric feel, in terms of both program and performers. Joining in the festivities will be Marje Palmieri and Joyce Bouvier, soprano; Vasily Popov (plus family) and Julia Goudimova, cello; Gwyn Jones, flute; Nancy Genovese, clarinet; Dilyana Kirova, bassoon; and Stephen Brown and David Ehrlich, piano. On the program will be works of Tchaikovsky and Shostakovich, together with Bach and Mozart, and some wonderful Italian baroque songs. Admission is free, although the Waterfront Village, who sponsors the concert, will greatly appreciate donations.
