No, this is not a family picture from some guy's wedding. These are the twelve (!) members of Puerto Rican Power, a salsa orchestra that's been around since 1970. They've seen it all: they've played with Celia Cruz, Cheo Feliciano, Ismael Miranda and a load of other salsa stars. Tito Rojas started his career as a vocalist of the group. In fact, most of the salsa brava movement (a faster and naughtier salsa) we owe to them. (Check this page for an impressive list of CDs, awards, and international tours).
So it's not a surprise that "Se Ven Bonitas" is professionally performed and perfectly structured. These guys breathe salsa. Trumpeter (and director since '78) Luisito Ayala keeps things traditional, emphasizing on the dancefloor value of the song. Minor point of criticism: musically the song is quite varied, but the line "Se Le Ve, Se Le Ve" gets a bit boring after hearing it 50 times in a row.
