Acid Fest is the first hard rock & psychedelic festival in Rome since the 70's. I gladly produced all the artistic support for this first edition which hosts Hawkwind as headliners. Cogitatio Sonitus means "Meaning & Sound" and the image is inspired by a Paracelsus excerpt: over the vacuity of humanity (the weapons, flags and treasures) stands the virtue (the cubic stone) and over both, leaving the ground, stands the virtue shaped by the arts and culture (the eyed polyhedron), the solid stone of the virtue shaped by the vision of the imagination.
