ALÉAS is a cycle of 12 transdisciplinary creations, which combines music (acoustic and electroacoustic) and visual creations (drawings, collages, objects, photographs and videos) with original poetry. Stemming from cosmological reflections, these works question the conception that we have of the universe that surrounds us, through poetic journeys exploring nature and matter (including the five fundamental elements: water, air, earth, fire, cosmos). This creative work is inspired by the concept of diagonal sciences of Roger Caillois, a form of interdisciplinarity of knowledge, in which the invisible, the underground relations must be exhumed in order to allow the emergence of a new and more complex image of the universe. Thus, in these compositions, the intertwining of sounds, images and poetry triggers multiple perceptions in synesthesia, blurring the boundaries between reality, illusion and imagination. This first composition of the cycle, 'Streamed knowledge of solids' is inspired by the materials that form the earth. Although they seem at first sight to be inert substances, rocks carry within them their whole history. A multitude of elements from the past are inscribed in their geological constitution, shaped over millennia by melting, sedimentation and water runoff. The structure and shape of each stone tells us where it came from and how it came to end up in that particular and unique shape. Matter can thus reveal profound knowledge. The work is performed on the Hyper-Bass-Flute, an instrument on which multiple sensors captures the subtle tactility and movements of the performer. They interact with live electronic processing of the flute's acoustic sound, as well as with the photo and video images that are mixed in real time and vary constantly. All electroacoustic sounds of the piece are generated in real time from the sounds of the live performed bass flute. Only the voice of the poet was recorded to be added to this performance.
