It starts, appropriately enough, with Charles Ives's The Unanswered Question, which seems to hold its breath, and occasionally exhale in brief bursts of panic, as the new century unfolds. It ends with Dmitri Shostakovich's Chamber Symphony Op. 110a (based on his String Quartet No. 8), whose alternating sequences of anguish, alarm, and derision come as close as possible for absolute music to indicting its bloody history - eight CDs and over 30 works later.
