Indecipherable Text couples the first two electronics-heavy releases, Lambent Material (2003) and Talk Amongst the Trees (2005), of Portland, Oregon ambient musician, Matthew Cooper, aka Eluvium, skipping over the solo acoustic piano of 2004's An Accidental Memory in the Case of Death. The two-disc compilation from Melbourne independent label, Sensory Projects, includes three bonus tracks not previously featured on any North American Eluvium releases.
