I've written before about the podcast Song Exploder, in which Hrishikesh Hirway takes a song and breaks it down into it component parts. Through interviews with the musician and isolated tracks of instruments and voices, he explores the formative ideas and decisions that created the track. If I had to pick a favorite podcast, it would get the nod.
This particular show is utterly amazing, because it describes the unexpected results when The Long Winters brought in guest drummer Matt Chamberlain, described as "the best in the country" to lay down tracks on their tune The Commander Thinks Aloud. Chamberlain played 5 tracks, one after another, then... well, it's pretty cool to hear songwriter John Roderick describe it.
