Pathline #1 is an audiovisual live set by Franz Rosati. It represents a virtual creature with its own behavior, sound and form, used as a synthetic metaphor to depict a mutation from a natural organic landscape to an artificial urban landscape. The visual structure, composed by simple lines and dots reminds us a vegetal agglomeration such as the branch of the trees or moss agglomerate, and it morphs following those natural rules, in a constant balance between chaos and order, through three steps in which is the sound to give voice to the tension of the morphing structure. Spasms, tortions, vibrations and high speed rotations, generates distorted sound and out of control sounds of nature, suffocated by the noises of a breathing city, through crescendos and sudden comebacks to silence. Probabilistic distributions and chaos theory, become the necessary technological tool to portray a concept beneath the daily life but anyway existing as an unchanging rule out of time.
