Amazon.com's Best of 2001 　　There's an alternately ethereal and electric power pulsing through Gozo Poderoso, the stellar fifth album from Colombian duo Aterciopelados. Maybe that's because the team of vocalist-guitarist Andrea Echeverri and bassist Hector Buitrago have rooted their sound in traditional rhythms while deftly dipping it in some of today's most exciting genres. Each track on the album flows effortlessly into the next, but there's nary a hint of repetition. It's all tied together by intricate production and a spiritual intelligence that flows through many of the song lyrics. "Luz Azul," "Esmeralda," and "El Album" (the first single) are stand-outs, anchored by Echeverri's slyly seductive vocals. Cumbia, salsa, and vallenato intermingle with alt-rock riffs, electronica flourishes, and bossa nova rhythms. It's an intoxicating mix that's impossible to classify--and resist.
