Go here, click on the link "Listen to Hour 1" and fast-forward to 47:08. You'll get to hear the Kronos Quartet perform "Flugufrelsarrin (The Fly Freer)" by Icelandic musical deity, Sigur Ros. It's beautiful.

You don't have to listen to me, btw. You can just go hear the whole set of two recordings if you'd like. I won't stop you.
