The recording is transmit by infinite_coil and it's a wonderful example of guitar based ambient. I've been using this as sleep music for the last week or so, works perfectly.
The music comes to us from Tom Lindsey, the curator of the excellent Spaceman's Transmissions mix blog. You can also find Tom's mixes on Mixcloud here... tonepoet.
Tom also has a recording he did with a friend under the name harmony & decay. It's on Bandcamp as well & is definitely worth downloading. I'm sure I'll be working both of these recordings into future mixes.
