Envasaré is the future tense of the verb envasar, which means 'to pack,' 'to bottle,' or 'to can,' usually in the context of preserving food.
In this song, Miguel Bosé creates a striking and unusual image by singing, "Envasaré mis besos al vacío" (I will vacuum-pack my kisses). This is a poignant metaphor for the end of a relationship, suggesting he is sealing his kisses away forever. It powerfully conveys a sense of finality and the preservation of a love that is now in the past.
This duet between Spanish-Italian star Miguel Bosé and actress Penélope Cruz is about a breakup so final, it's almost theatrical. They're not just splitting up; they're making sure no one can ever come back. The song opens with instructions for the last person to leave: “El último que apague la luz / Que tire las llaves al fondo del mar” (The last one to turn off the light / To throw the keys to the bottom of the sea). It seems this couple has been here before, as they admit “lo que siempre hicimos fue decirnos adiós” (what we always did was say goodbye to each other). This time, though, it's for good.
The chorus describes this final goodbye as turning everything black, using intense images like “Como la boca de un lobo” (Like a wolf’s mouth) and “Como un pozo sin fondo” (Like a bottomless pit) to describe the darkness. The song is full of these kinds of dramatic, slightly strange lines. He plans to “Envasaré mis besos al vacío” (I will vacuum-pack my kisses) and dance his last tango alone. Even though they accept the end, the pain is clear. He sings about how much it hurts to lose her laughter and her summer, finally accepting his life in this “mala muerte” (bad death).
