They are a five-piece electronica outfit from Glasgow. Their debut album Clutter was released in 2008 and they did a Radiohead and asked fans to pay what they wanted for it.
It's been described as folktronica (hmmm) ambient trip hop (okaaaaaay) and lush space jazz (just no!).
Despite those (somewhat lame I think) attempts to categorise it, it's a wicked song.
Have a little listen here.
