Ever hear of Jan Dismas Zelenka? Well, the Bach Sinfonia calls Zelenka "the Bohemian Baroque," and says his rich and colorful output equals that of his better-known European contemporaries, including Rameau, Handel and J.S. Bach. The Sinfonia presents the first hearing in North America of the German composer's complete cycle of The Capriccios, composed for the courts in Vienna and Dresden after hunting parties. Saturday, May 5, at 8 p.m. Cultural Arts Center at Montgomery College's Silver Spring campus, 7995 Georgia Ave., Silver Spring. Tickets are $30. Call 301-362-6525 or visit bachsinfonia.org.
