After the "A M.B. Iehn Tale" release (CD - SmallVoices 2005) for the first time Maurizio Bianchi meets TH26, historical Italian project in dark electronics. After their first official release ("La Haine" CD - SmallVoices 2002) they are now back with this amazing cooperation. For this release TH26 leaves their usual rhythmical attitude, in perfect symbiosis with Maurizio Bianchi, the "father" of Italian industrial music. This work presents deep obscure minimal soundscapes, moving in the fields of dark ambient music. Arkaeo Planum is a long deep 5 tracks trip through 5 interlinked themes (Aereo, Arkaeo, Audio, Caro e TerraPlanum) togheter with a single special track titled MB Sorrow (dedicated to Maurizio Bianchi) as final sadly sequence of melting melody. Sound textures with piano incursions and samples, properly treated by M.B., involved in a magmatic and dark isolationist sonority, made by Th26.
