MSBR (Molten Salt Breeder Reactor), aka Koji Tano, was one of the most respected noise artists to arise from Japan's exciting noise/experimental music scene of the 1990s. Much of his material was self-released on his own label, the astounding MSBR Records, which was dedicated to the production of limited-edition releases with incredible artwork. MSBR present a music elaborated with previously chosen source of sounds, whose origins are either naturel or artificial, with use of Korg guitar synthesizer and some effects, working in analog sounds. Oscillating between grappling electro noise (as he describes his musical style) and pure noise, the really surprising quality of the sound research leads to a tremendous kind of noise-texture. Ultimate Ambience is his debut album, recorded in February 1991 and released the following year on its label in 400 copies (the first one hundred copies in special edition with in unique fold-out handmade covers using foil, paint, and collage elements). Tano's Molten Salt Breeder Reactor divided record into two long tracks filled with excellent harsh noise with strong influences of musique concrete and electro-acoustic. The great production on this LP makes it so powerful that it is frightening at times. Layout by Yoshihiro Nakano.
