Follow-up to 2003's Ourselves by this Glasgow duo finds them extending the already broad range of sound heard on that stunner into new worlds. The two prolific players heard here are at the top of their game, pairing some immediately identifiable elements - Neilson's superb jazz-influenced drumming, Youngs unmistakeable voice - with a thick layer of truly psychedelic clamor. The brief "Chamber" rips out a noise like a 60's Ra/Patrick duo, segueing into the also Ra-ish masterpiece "Music of the Lost Sun." The point in "Lost Sun" where Young's voice and guitar emerge from the polygot sound for a beautiful melodic interlude is just too much. The second half of the record has a less layered feel, beginning with the acapella "Noatak Beacon," then moving into more aggro territory with Neilson's bowed cymbals taking on Youngs' guitar on "Mountain." The short cut-up "Big Aeroplanes" ends the record on a final note of mystery.
