Sbrocco is a colloquial and expressive Italian verb, derived from "sbroccare," which means "to lose one's temper," "to freak out," or "to snap."
In the context of the song, Salmo uses it to convey a strong emotional reaction: "Che se non ci sei, io sbrocco" (Because if you're not here, I lose it). It highlights the intensity of his feelings and dependence on the person he's singing about, making it a vivid and relatable expression of emotional distress.
MATRIOSKA is a love song, but the person it is sung to is not a person. Salmo and Noyz Narcos address a drug the way you would address someone you cannot stop going back to, and they never once name it.
The clues are all in the small details. The singer waits for a call "as Christians await the Messiah", says he has been "on this shit since '98", and admits he took her "around the pharmacies". The chorus is pure high: tu mi fai sentire in volo, you make me feel like I'm flying, vedo molto meglio da qui, I can see much better from here. Then the comedown arrives in the same breath, e ora che mi lasci da solo, and now you leave me alone, and the whole thing collapses into one question asked three times over: where are you?
The verses fill in what that costs. He drives the wrong way down the lane, rolls over in bed alone even when she is there, and loses his temper the moment she is missing. Noyz Narcos takes it back to school toilets and a first criminal charge, which turns the habit into something that has been growing quietly for decades rather than a bad night.
The title carries the idea. A matryoshka is a doll with another doll inside it, and another inside that. Every time he opens one up hoping to find the thrill again, there is only a smaller version of the same thing waiting.
