The pairing of Puente and Santos Colon began with the best-selling Dance Mania, and this latest reunion finds them again at the top of their game. "Mas Bajo" is a Prado-esque mambo, and "El Agitador" is largely a fast-paced, contrapuntal horn exercise. Salsa, cha cha cha, guaguanco, bolero, and other rhythms are represented. Colon sings without affectation, perfect for the assured playing and dramatic arrangements of Puente. While there is plenty of talent, great songs, and an easy style, the album is missing the single, progressive, "killer track" of which the pair is capable. "A Gozar Timbero" is close, but it sounds a decade older than it is.
