Reissue of the double cassette releases in 2010 on Second Sleep, by the duo of Matteo Castro and Riccardo Mazza. Hailing from the farthest North-East glacial tip of Italy, Lettera 22 utilize elements of musique concrete sound sources, delicately sampled, looped and edited; here is a heavy focus on textures and harsh noise with bouts of restraint and full assault, as usual via analogue tapes manipulation and feedback.
