Ben's currently working on a album and on his site, you can listen to the following err.. tracks.
"A long way down Every single noise in this track is a field recording. It contains the sounds of relays controlling a lift at Earls Court and various trippy noises from deep in the tunnels.
Escalating The beat is based around the noise of one of the escalators at Moorgate station recorded from underneath and slowed down. There's a hacksaw and an electromagnetic brake in there as well.
Silhouettes The machine that forms the basis of this track cuts running rails to prepare them for assembly. The rail traverses back and forth against a cutter which removes the steel in shavings which you may hear falling on the ground. Whispering, humming and singing are all provided by the wonderful Plum."
Not sure if they'll be on my iPod but an interesting concept if you want to take the sounds of the Tube home with you, or dance along to them at a club.
