Brivido literally means "shiver" or "thrill," a word you might use for a chill from the cold or a jolt of excitement. It's a wonderfully expressive word that captures a physical sensation.
In the song, Måneskin uses it poetically: "Era un brivido che porta la luce dentro le tenebre" (It was a thrill that brings the light into the darkness). Here, it's not a shiver of fear, but the electrifying feeling of change and salvation. It's a powerful metaphor for an experience so intense it can illuminate the darkest of times.
This song is a desperate and beautiful plea for someone named Marlena to come home. The singer feels lost without her, singing, "Quindi Marlena torna a casa / Che il freddo qua si fa sentire" (So Marlena, come home / Because the cold is making itself felt here). He's afraid of fading away completely without her by his side. She is the one who saved him when he was at his lowest, covered in thorns and snakebites. She gave him the courage to start a new life and a new journey, and he promised to walk with her until their hair turned white.
But who is Marlena? For Måneskin, she's more than just a person. Marlena is their muse, a symbol of freedom, creativity, and life itself. When the singer describes his past as being "solo un pazzo" (just a madman) with a crumpled jacket and cuts on his wrists, he's talking about a life without this inspiration. Marlena is the force that brought "luce dentro le tenebre" (light into the darkness) and freed him. So when he begs her to come back, he's calling out for the very spirit that makes him feel alive and able to create.
