Alice - Tom Waits
Black Sheep Boy - Okkervil River
Schubert piano duets - played by Sviatoslav Richter & Benjamin Britten (this is not the disc I have, but the most similar one on Spotify)
Rook - Shearwater
The Sunset Tree - The Mountain Goats
Mahler: Lieder - sung by Christian Gerhaher
J Roddy Walston & The Business - J Roddy Walston & The Business
The Chairman Dances, Tromba Lontana and Short Ride in a Fast Machine by John Adams. I also played Harmonielehre, Parts 1, 2 and 3, which are on Spotify but would add another 40 minutes to your listening and you might not quite have time for that this afternoon. My recording is played by the CBSO, conducted by Simon Rattle.
Oh, and a late addition - many of you will have seen Google's tribute on Jim Henson's birthday. Thanks to Jonco for directing me to this.
