Mambo Sinuendo is a collaboration between Ry Cooder and Buena Vista alum (and formerly of many other groups as well) Manuel Galban. The album attempts to catch an old style popularized in Cuba by Galban, and was, surprisingly, never followed up on by anybody after Galban. It's a guitar-based romp closely based in the pop/jazz crossovers of the 1950s-1960s (Henry Mancini, Nelson Riddle, etc). There's a touch of exoticism here and there, and a larger touch of a relatively Hawaiian feel throughout the whole via the guitar techniques employed by the pair. It's all somewhere in a form between lounge, mambo, and Esquivel's old space-age-bachelor-pad music. In rare instances, there's even a little bit of a house drum loop added in by the percussionists.
