Well the intros to "Everything in it's right place" and "Treefingers" are sorta like it, but they aren't the ones you are looking for I don't think. I recognize the synth in the song you posted.. I just can't place it!
Arg.. now I must find out too.. lol. It sounds really familiar, but I can't remember where it comes from..
*edit* Check out the song "Sit Down Stand Up" by Radiohead.. the synth in that song is very similar to the one in the beginning of the song you posted. Also, check out "Sail to the Moon".
Alot of the songs on Hail to the Thief are reminding me of the song you posted.
*edit* Ahhg.. I can hear a radiohead song in my head, but I can't remember the name.. I don't have all my music with me right now, so I can't browse through and listen. I'll keep tryin to find it though.
