Two circular interactive installations provide immersive sonic experience when tactile sensors are activated. The multi-sensory installation combines elements of a fire — stone and wood — a symbol of sharing knowledge and rites. One circle transmits vocal sustained notes, creating a set of rich and dense harmonies, and the other one responds with vegetal organic granulated tones. A dialogue between man and earth, a reflection around a “deconstructed” fire. Inspired by nature and its symbolic representations of spheres in culture. This interactive sound installation embodies the vibrations of life and the unification of voices.
