“Fortune Favors the Bold,” will features the first of Beethoven’s many ventures in the stormy key of C minor: the Piano Trio in C minor, op. 1, no. 3. The program also includes the “Kakadu” Variations, op. 121a, a work that Beethoven tinkered with almost his entire adult life. Stephanie and Jeffrey will perform Dick Kattenburg’s no-holds-barred, jazz-inflected Sonata for flute and piano. The second half of the concert again features accordionist Stas Venglevski in bold works by Stas and composers from Eastern Europe.
