Clessidra translates to "hourglass". It's a beautiful and somewhat poetic word that isn't commonly found in everyday conversation or many pop songs.
In the lyrics, the artist sings about "Una spiaggia infinita che fa da clessidra" (An infinite beach that acts as an hourglass). This metaphor evokes a powerful image of time passing slowly and endlessly, using the vastness of the beach to represent the sand in an hourglass. It's a unique and thought-provoking image that adds depth to the song's reflective mood.
Ultimo and Mezzosangue team up for "DILUVIO UNIVERSALE," a song that really gets into the head of someone who feels everything intensely. Ultimo kicks it off, talking about having a "cuore sotto i piedi" [heart under his feet] but the "anima di un samurai" [soul of a samurai], suggesting a deep resilience despite past pain. He feels things so strongly that even a single drop of rain can feel like a "diluvio universale" [universal flood] to him, just like a tiny ant experiences an explosion from a single drop. It's a powerful image for someone who processes the world with such sensitivity.
He grapples with overthinking, admitting, "se penso troppo è perché sento tutto" [if I think too much it's because I feel everything]. There's a longing to be someone who doesn't question everything, someone who "odia farsi domande" [hates asking questions]. But ultimately, he finds solace and an outlet in music, describing it as his only friend, a "spiaggia infinita che fa da clessidra" [infinite beach that acts as an hourglass] for him to sing. It's a really honest look at the struggle and beauty of being a deeply feeling person in a sometimes overwhelming world.
