And another young varón thinks he has a shot at the Luis Miguel throne. You get the impression he's studied Miguel closely: not just the histrionic vocals, but the bolero rhythms, the expansive production, and even the record sleeves, where he stares off into the distance with smoldering sexuality in his eyes, shout that this is a teen idol who wants to be taken seriously as a romantic pop star.
He comes of good show-business stock, this young Castro: his mother was a noted singer and actress, and his father was a comedian and actor, one of the Valdés clan who popularized pachuco comedy with Tin-Tan in the 1940s and 50s. A child actor in the eighties, he released his first album when he was eighteen. A year later, he released Un Segundo En El Tiempo, from which this song was the first single.
It's a strong song, originally performed by the norteño outfit Grupo Bronco in their pop-friendly Mexican-country style. Castro adds such modern (i.e. "rock") signifiers as an alto sax and turns it from a two-step into a power ballad, emoting his guts all over the place. Luis Miguel has nothing to worry about; the kid has none of his sense of restraint or timing, and oversings it rather badly. The music holds up its end, and he doesn't manage to embarrass himself too much — it was after all a significant hit, and will become one of his signature songs — but in terms of 90s Latin pop idols, he along with everyone else, dwells very much in one man's shadow.
