Pacifica Quartet and the Supremes The U.S. Supreme Court is not necessarily a place one would expect to find a concert. But every year early in May, the Justices get together with several hundred invited guests to listen to music. This time around, the Pacifica Quartet was invited to play, and Performance Today was there to record the concert. The Pacifica Quartet plays the String Quartet, Op. 44, by Mendelssohn.
