Solarisation is a collection of five excerpts from practice improvisational meetings that Morphogenesis carried out on a regular basis between 1991 and 1993. It shows the group coalescing into fairly regular roles of foreground and background, where the background is typically a steady-state drone of some kind, and the foreground is some kind of amplified tiny sounds, percussion, or perhaps a radio broadcast. Within this framework there is of course a wide variety of possible sounds, and Morphogenesis manages to produce and exploit several combinations. "Entropy," for example, features a quiet background drone with gongs, prepared piano, and a news broadcast, evolving through an extended unprepared piano interlude to a zither-like sequence with undulating waves, returning to piano chords in the lowest register and wheezing rattles. "Seeds of Crystallisation" starts with a brilliant enveloping, almost rain-like sound, brings in a table-top guitar, gongs, hisses, electronic roars, and almost recognizable recordings, before it finishes with loud electronic sweeps. Everything evolves organically, with layered gestures seamlessly integrating one to the next, and with no overt virtuosic displays, the group manages to concoct previously unheard sound worlds, indescribable and enveloping, but with enough sonic detail to keep the work interesting across multiple listenings.
