"Void Beat", by Cavern of Anti-Matter.
It is quite possible that, with "Void Beats / Invocation Trex", Tim Gane and his merry pranksters have come up with the perfect album for the shuffle age.
Well, the album itself is of such a length that it tends to become a bit of a chore to listen to all the way through. (This is, perhaps, not surprising. Stereolab weren't always free of that particular problem.) However, if a song from the album shuffles up to the surface during your daily commute, I can personally guarantee you (or your money back!) that it will be the freshest, and most surprising, thing you will hear during your journey. It doesn't matter which song it is, or how long your commute is. You can trust me on this.
Case in point: tonight I got "Void Beat". I can't find a link to the album version, but here they are playing it live. What a thing is this modern world, eh?
(Note, in passing, how Gane's guitar at the start of the song seems to have walked straight out of "Pictures of Matchstick Men".)
