Quebre comes from the verb quebrar, meaning to break or shatter. While romper is a more common word for 'to break', quebrar often implies a more profound or emotional breaking, like a spirit or a heart.
In this song, the singer uses quebre to describe how the memory of a lost loved one still deeply affects him, causing him to break down emotionally: "Su recuerdo viene y hace que me quiebre" (His/Her memory comes and makes me break). It's a poignant word that conveys deep sorrow and vulnerability.
Have you ever just wanted to make a call to heaven? That's exactly what Grupo Arriesgado sings about in "Una Llamada Al Cielo." It's a really emotional song where the singer is missing someone who has passed away, an "angelito" [little angel] as he calls them. He's trying to be strong, but he admits, "todavía me dan muchas ganas de llorar" [I still really feel like crying].
He talks about how things aren't the same without this person and how even though he's achieving the things he promised them, "si no está no sabe igual" [if they're not here, it doesn't taste the same]. He feels like his soul is incomplete, like a part of him left in their suitcase. He just wants to hear their voice, even for a moment, and asks them to "no olvide aparecerse en mis sueños" [not forget to appear in my dreams] so they can still see each other, even if it's just like that. It's a really heartfelt look at grief and longing, and how you carry someone with you, like a tattoo on your skin.
