"Defunkted" [mp3 removed]
There was a postpunk jazz group called Defunkt but this is kind of the opposite of that (as in, heavy use of default xylophone). All sounds made with Linplug's Element P rhythm softsynth, plus some midi effects.
Update: Made the xylophone a shade quieter in the first 20 seconds but jeez it's penetrating. It could be used by the military to make dictators come out of their houses.
