October 4. Founded in 1978, the Rhinebeck Chamber Music Society has been presenting concerts at its second hometown venue, the Church of the Messiah, since 1982. The society ushers in its 37th season with this sumptuous pairing of violinist and violist Helena Baillie and pianist Babette Hierholzer. Baillie (who, incidentally, curates the local Classics on Hudson chamber series) has performed throughout Europe and the US and collaborated with Pinchas Zukerman, Midori, the Tokyo String Quartet, and the Beaux Arts Trio. Hierholzer has performed internationally as well and appeared with the Berlin Philharmonic and other prestigious orchestras. 3pm. $25 ($5 for students). Rhinebeck. (845) 876-3533. Rhinebeckmusic.org.
