Amazon.comThe compositions on Béla Fleck and the Flecktones' three-CD set Little Worlds are ambitious, audacious, and, at times, a bit absurd. The musicianship of Fleck and his compatriots bassist Victor Wooten, saxophonist/flautist Jeff Coffin, and electro-percussionist Future Man is as accomplished as ever. Even when they are engaging in a slice of silliness like their version of "The Ballad of Jed Clampett," which they re-imagine as a sort of a rap rhapsody, the intelligence and sheer inventiveness of the performers keeps the music from descending to a trivial level. The 27 tracks are practically swarming with guest artists from a wide range of traditions, including Bobby McFerrin, Branford Marsalis, Nickel Creek, the Chieftains, Fleck?s former New Grass Revival band mate Sam Bush, and the Tuvan throat singer Congar Ol Ondar. Perhaps the most intriguing visitors are Pamelia Kurstin, who plays Theremin on a number of tracks, and Jake Shimabukuro, a remarkable young ukulele player from Hawaii. The music on Little Words combines experimental sonic textures, complex harmonies, intricate rhythms, and charming melodies with impressive instrumental chops. Béla Fleck and the Flecktones are serious musicians, but their music, which is infused with joy, is never somber. --Michael Simmons
