On their delirious second album, these Mexico City rockers get cosmic with a retrofuturist foray into old-fashioned '60s psychedelia. Synths rule on opener "Nuevos Amigos" (New Friends), which sets the stage for ambitious studio experimentalism like the constantly fluctuating "Mala Onda" (Bad Vibes), the jamming dance rock of "Trágame Tierra" (Swallow Me, Earth), and the extended Pink Floyd-influenced space funk of "La Luna" (The Moon). Río Savaje (Wild River) concludes its whitewater journey in "TQM" with a glorious Beatles flourish.
