From the liner notes to her 2008 album, Merengue Típico from the Dominican Republic:
The song that made La India famous in the early 1990s, this merengue is in the mambo-based style that was then just beginning to bring típico back into the public eye. Tho first mambo section starts at about 2:00; a second mambo enters after the next verse, and is filled in with bass and conga solos.And what solos: short, inventive, fun solos. Electric bass may have replaced marimba in merengue típico bands, but — pay attention! — between 2:52 and 3:04, the bassist Alfonso González Perdomo is doing his fantastic imitation of marimba sound.
