We've dedicated this week's show to an often-misunderstood figure from late 20th-century music - Karlheinz Stockhausen.

Composer/violinist Christopher Tignor has worked with a healthy cross section of the new-music community, from Brooklyn Rider string quartet to the conductor-less string orchestra A Far Cry. He also leads the bands Slow Six and Wires Under Tension. Hear his mixtape today at 3 pm.
