A backstage, a video-interview, a visit to the scene. Probably none of the above, as suggested by the double negation of the title.
Shot during the shooting of La Sintesi's videoclip for their single "Curiosità", the video is a light-hearted declaration of emptiness. The blue emptiness of the virtual fishbowl where the band members float, the emptiness of pop music as a phenomenon based upon collective make-believe, the emptiness of words that chase each other without reaching an ultimate meaning (but this is maybe their real meaning).
As instruments get muted in a mocking oxymoron, the (only?) right allowed to the musicians is the right to speak, the duty of "bullshit" ("prank" in the timid subtitles).
