The Chameleon Arts Ensemble presents an afternoon of breakthrough works for cello and piano, featuring Rafael Popper-Keizer, called a “local hero” by The Boston Globe, and pianist Vivian Chang-Freiheit, praised in The Boston Musical Intelligencer as “[Her] playing was soulful, passionate, and her sense of ensemble brilliant.” The Goethe-Institut will be transformed into an intimate cabaret setting with table seating and a complimentary glass of wine, and the concert will be hosted by Artistic Director Deborah Boldin. The program includes one of only three chamber works by Richard Strauss, his Sonata in F Major, Op. 6, an early piece that is rooted in classical traditions but filled with his burgeoning heroic voice; Frank Bridge’s Elegie, striking for its simplicity and elegance; Elliott Carter’s monumental 1948 Sonata, which stands at the crossroads where his early neo-classical style meets the modernist he would become; and Beethoven’s famous A Major Sonata, Op. 69, the first truly equal duo sonata for cello and piano.
