As its title suggests, Mexican director Alejandro González Iñárritu's film revolves around the transcultural difficulties of human communication. But the linguistic dysfunction that drives the film's characters towards causal connection and inevitable tragedy has paradoxically inspired just the opposite on this adventurous musical mélange of a soundtrack. The meditative, often hypnotic fretboard inventions of Iñárritu's previous soundtrack collaborator, Argentine composer Gustavo Santaolalla (a 2005 Oscar winner for Brokeback Mountain), serve as the restless soul of interlocking plots in the film, the final chapter of a fatalistic trilogy that also includes the Santaolalla-scored Amores Perros and 21 Grams.But on this expanded, double-disc collection, the South American composer's culture-bending film cues (including mastery of indigenous Arab stringed instruments and incorporating field recordings of Moroccan tribal music) also serve as artistic axes, reflective anchor points for a pop collection that's as ambitious and far-ranging as the film itself. While the "music from and inspired by" tag often indicates cynical record company marketing schemes, here it's an invitation to transcultural musical adventure that links Santaolalla's North African musical conjuring with the contemporary styles of Japan (the atmospherics of Ryuichi Sakamoto and Susumu Yolota, Shinichi Osawa's sly Earth, Wind & Fire/Fatboy Slim mashup, the teen pop of Takashi Fujii's "Oh My Juliet") and Tijuana (a generous sampling of effusive Norteño that includes Los Incomparables, Daniel Luna, and Agua Caliente). --Jerry McCulley
