Cone Concert Middleground (Shelley Washington) and String Quartet No. 14, Opus 131 (Beethoven) The Jasper String Quartet is one of the great young quartets in the world today, and one of the few equally at home playing music old and new. For this concert they do a little of both, playing a recent, spectacularly propulsive work by young composer Shelley Washington, and a classic: Beethoven's C? minor quartet, opus 131—one of the longest, most intensely personal, and most powerful quartets ever written, and one of Beethoven's last works.
