Following the white "Ten Numbers", the black "Ten Letters" follow the same guidelines and format (a double digipack featuring an audio CD and a DVD), but present Spyweirdos under a totally different guise: the CD is mostly drone and field-recordings based, with less beats or glitches, and works more as an works in accoustics (unsurprisingly considering Spyweirdos's field of expertise) than as "songs" or "tracks". The DVD itself contains slow evolving, futuristic and aesthetics interpretation of Spyweirdos's material by Aris Michalopoulos, and works pretty well in conjunction with the music. Another very interesting and deep release by a very talented musician.
