Walter Maioli from Aktuala and Futuro Antico, and Agostino Nirodh Fortini, lifelong specialist in the application of sound and image to therapy and meditation, starting out with the breath of a stem, slowed down and filtered, in this musical expression of the psychoacoustic qualities of plants — ‘the organic symbiosis, real and mysterious at the same time, between the pharmacological properties of the plant and the sounds it emits… a vibration permeating the whole Universe.’

‘Investigations of the secret dialogue between the trickling of pond waters and the faint percussive reverberation of stalactites and stalactites. Rocky sediment played as tubular organs, glockenspiels, xylophones, stone marimbas. Crystalline timbral variations and subtle microtonal passages recall the chimes of Tibetan gongs and bells, the scales of Java and Bali. Amidst muffled pauses and silences, trills and rings, echoes and tremolos, hisses and pops of vibration, Maioli — often responding directly to polyrhythms created by dripping and falling water — builds his most imaginative sound-world.’

Says Maioli: ‘Beginning in 1986, my daughter Luce and I started experimenting with sounds in the spectacular caves of Toirano. We lived in this Ligurian town for three years at the beginning of the 1990s. A total immersion in prehistory. There are traces in the Upper Paleolithic of repeated percussion on stalactites and stalagmites. Not all stalactites and stalagmites make sounds when struck, but some reveal truly extraordinary and incredible sounds, from powerful low gongs to subtle, crystalline sounds. We also recorded (exceptionally) these fantastic sounds in the caves of Borgio Verezzi by hitting the stones directly with our hands or with special clappers so as not to damage them, with the supervision of the speleological guides.’
