Relámpago translates to "lightning flash" or "flash of lightning." It's a vivid and evocative word that isn't commonly found in everyday song lyrics, making it stand out.
In the song, the phrase "Un relámpago azul" (A blue lightning flash) is used to describe a sudden, intense, and perhaps fleeting moment or memory. It adds a touch of poetic drama and mystery to the recollection of a past relationship, suggesting a powerful, almost magical, event.
Have you ever seen a picture of an ex looking happy with someone new and felt a little... short-changed? That's exactly where Funambulista takes us in "Cadaqués." Our singer sees a profile picture, a trip to Cadaqués, and those beaches his ex was looking at with "el tipo aquel" [that guy]. It "me supo a poco" [tasted like too little] – not enough for him to move on, apparently, because he writes to her, asking if she dares to return to "aquel café del centro" [that downtown cafe], just like in 2003, with "nada que perder" [nothing to lose].
But it's not all about getting back together. The song is full of these beautiful, almost dreamlike memories: "Un relámpago azul" [A blue lightning bolt], "esa lluvia de Agosto mojando tu pelo" [that August rain wetting your hair], and "la canción que escribimos con tiza en el suelo" [the song we wrote with chalk on the ground]. He remembers her saying "loco, no vayas por ahí" [crazy, don't go there] because "los besos imposibles nunca acaban bien" [impossible kisses never end well]. Even though he thinks of her, they both know "mejor dejarlo así" [it's better to leave it like that]. It's a bittersweet look back at a past love, full of vivid flashes of youth and the lingering feeling that some things, even if they're over, still leave an impression.
