RAINBOW is the sound of hot noise rock act Boris, featuring Japan's preeminent psychedelic lead guitar player Michio Kurihara. for such a formidable combine of noise-making rock and rollers, there is much open space in RAINBOW. Sometimes akin to a topless chasm extending forth into the firmament, RAINBOW is also a horizonless atmosphere, with Boris' spacious trio creation scorched by traces of Kurihara's skywriting guitar leads.
