Background music

[HGL1]

The BBC has recently been running an advert about the licence fee and that now with new technology they can find anyone who has a TV but is not paying the licence fee. The ad begins with a helicopter sound and the camera hovering over a computer processor/motherboard and it is shot in such a way as to make the computer chips and other parts appear to be a cityscape. The voice-over talks about the technology and says "It's all in the database". The advert is accompanied by some very beautiful and atmospheric guitar music. Does anybody know what the song is called and who performs it?
