“Morene” is the result of a close collaboration with the eclectic bassist Manu Mayr. We had several work sessions at his studio in Vienna, starting from abstract ideas, developing together the piece’s sonic material, defining pedals set-ups and at last rehearsing and recording the final score. The three movements of this composition – Triti (trite/crushed), Ritriti (trite, several times), Detriti (debris) – are meant as different expressions of a main, common idea: a geological image. Moraines – sediments of glacial debris – have a double process, both of accumulation and deterioration, erosion, fragmentation. Following this concept, the double bass – amplified and processed through 2 pedals – becomes at the same time the place and the tool for material’s accumulation and corrosion, where repetition leads to sound erosion, where lines becomes points, grains, vanishing dust.
