Julliard String Quartet - DEBUSSY String Quartet in G minor, Op. 10
String Quartet in G Minor, Op. 10 - Debussy
Ok, this was written in 1893, so it's a bit outside the bead's specification. But it was very influential on 20th century music, especially 20th century chamber music and string quartets. The only string quartet that Debussy wrote. Performed here by the Julliard String Quartet.
