*200 copies limited edition* At the end of the 1980s, Mariolina Zitta approached the world of natural sounds, studying musicology and developing a passion for speleology. Her encounter with Walter Maioli was fundamental, guiding and influencing her definitive research into sound archaeology and the primitive sources of musical acoustic phenomena. In these recordings Mariolina conducts a magical ritual as a cave priestess, celebrating the icons par excellence of the mysteries of the night: bats. The specific frequencies of the calls of these fascinating creatures are recorded with special detectors used by ecologists, and the result is an organic synthesizer. The fusion with the sounds of natural objects (stones, stalactites, logs, bone whistles, Tibetan bells, mouth bows, trumpet shells) and the vocal modulations of harmonic singing allow listeners to travel into a still unexplored sound dimension, through an evocative experience of total sensory listening. It is an arcane landscape filled with pure vibrations, magnetic resonances and aquatic sounds; an ancestral enchantment on the border between consciousness and dreams, a symbolic liturgy of primordial reverberations, echoes and whistles.
