Joan Kwuon and company take on Mozart and Brahms at the Library of Congress

Two predominantly stern Germanic piano quartets monopolized Friday evening's concert at the Library of Congress. Violinist Joan Kwuon, violist Joel Smirnoff, cellist Sharon Robinson and pianist Sergei Babayan (all Cleveland Institute of Music professors) were engaged to play Mozart's Quartet in G minor, K. 478 and Brahms's Quartet in G minor, op. 25.
