Gregor Hildebrandt's *Au Claire de la Lune (o.a.)* exemplifies the German artist's signature practice of repurposing magnetic tape from cassettes and vinyl records as a primary artistic material, embedding music and memory directly into the physical surface of the work. The piece transforms the nostalgic French folk song referenced in its title into a visual and tactile experience, where the recorded sound becomes inseparable from the form itself. Hildebrandt's work occupies a space between conceptual art and painting, inviting viewers to contemplate the invisible layers of audio history preserved within the material.
