While musicians proceed to construct parts that will only come together as pieces in the editing room, Xavier Braun captures this process which takes registration as material in a mimetic fashion - a documentary that turns to the generation of junks that constantly dissipate their crystallization into a whole, bringing forth a combinatorial logic, an eternal game of divisions, sums, and repositionings. Musical composition being guided by the principle of montage and editing centralized in the amplification and systematization of the gesture, QUIPROCÓ has at its core the thread that traverses both the making of both cinema and music: the space of memory formed through the succession and juxtaposition of things in time.
