Desvelan comes from desvelar, a wonderfully flexible verb that can mean “to keep someone awake” or “to reveal something.” In the song, “lo desvelan a uno” most naturally suggests that the departing muses keep him up at night, capturing the restless, emotional aftermath of inspiration and heartbreak.
Sabino’s “Principios De Septiembre” begins with a wonderfully blunt surprise: “¿Cómo que siempre no?” [“What do you mean, actually no?”]. He had already told his friends and had started writing a love song, so the other person’s change of mind leaves him scrambling. Instead of turning bitter, he says, “Gracias por avisarme a tiempo” [“Thanks for telling me in time”]. Their moments were few, but he still calls them beautiful, and he respects the other person’s decision to step away.
The song becomes more personal when he admits, “Si por mí fuera, me hubiera gustado una historia bonita” [“If it were up to me, I would have liked a beautiful story”]. He was only beginning to open up, while this person was already closing the door. The English line “You were too good to be true” means the person seemed almost perfect, perhaps so perfect that he should have doubted it. The repeated “¿Cómo que siempre no?” [“What do you mean, actually no?”] turns the disappointment into a funny, frustrated refrain. By the end, he sums up the short romance perfectly: “Se sintió infinito, pero duró poquito” [“It felt endless, but it lasted a little”]. Even the mention of the muses leaving suggests that this sudden change has disrupted his songwriting, keeping the song light while he admits that the moment really mattered.
