Performance Oklahoma presents Editions One and Two from the 2012 broadcast series celebrating chamber music performances from the 2012 OK Mozart International Festival. In the first hour, we’ll hear the sublime Zwei Gesange Op 91 for Contralto, Viola and Piano by Johannes Brahms featuring mezzo-soprano Sasha Cooke, violist Paul Neubauer and pianist Orion Weiss and Mozart’s Sinfonia Concertante K364 in a remarkable arrangement for string sextet played by violinists Ani Kavafian and Katie Hyun, violists Paul Neubauer and Andy Lin and cellists Peter Wiley and Mihai Marica. And to conclude the hour, baritone Kelly Markgraf and pianist Anna Polonsky offer Franz Schubert’s lively Die Forelle. Kelly returns in the second hour, joining violist Paul Neubauer and pianist Anna Polonsky to present the evocative Five Songs for Voice, Viola and Piano Op 5 by Charles Loeffler. Paul and Anna also join violinist Ani Kavafian and cellist Peter Wiley for a performance of the quartet for piano and strings Op 47 by Robert Schumann, the clarity and intimacy of textures in this relatively experimental genre of its time still surprising us even today. And, Andy Lin offers his first performance on one of the most beautiful of the traditional Chinese instruments, the erhu.The musical artists and special guest Bill McGlaughlin offer insights into the music and the art of chamber music collaboration.
