A podcast I really enjoy is called Song Exploder. In it, musicians pick apart the recordings of songs to explain how they were created, and you get to hear how the song was developed, track by track.
For the anniversary of the Space Shuttle Columbia disaster (February 1, 2003), I present you my favorite episode: The Commander Thinks Aloud, by The Long Winters.
I first listened to this on a terribly rainy drive to teach a model rocketry class last summer, and I've listened to it several times since. It's very moving.
