The Gipsy Kings are never going to have the kind of critical acclaim that Paco de Lucia has, but their popularization of poppy rumba flamenca among non-Spanish speakers is nothing to be ashamed of. Nonetheless, here on Roots, the octet turns back to the tradition while making their own imprint on it. Having the band record in an old farm house, producer Craig Street, it seems, simply told them to sit down to play their bittersweet songs. Without electric instruments or a drum set to clutter the mix, brisk acoustic guitars will sweep listeners up in the driving rhythms as lead guitarist Tonino Baliardo soars overhead, particularly on the instrumental songs. When Nicolas, Canut and Patchai Reyes take turns on lead vocals, Street adeptly captures the timbre and nuance of the singers' voices while also delicately balancing the guitar, hand percussion and bass. No pop songs or bombastic rock beats:here's one that purists cannot argue with. --Tad Hendrickson
