As if bluegrass (and even "newgrass") was too constricting, the quintet--Sam Bush (mandolin), Jerry Douglas (dobro), Bela Fleck (banjo), Mark O'Connor (violin), and Edgar Meyer (bass)--incorporates classical-style themes and arrangements within the context of bluegrass instrumentation. Their unbelievable technique and musical ability was never in question; however, what makes the album special is the uncanny blend of precision and freedom, of improvisation and structure. Each of the 10 compositions were written by a different twosome (do the math permutations). Playful bluesy lopes ("Pink Flamingo") accompany tinges of reggae ("The Locks of Dread"), Celtic ("Macedonia"), and Middle Eastern ("Blue Men of the Sahara") music. There are urgent burners, somber mood pieces, and tender ballads, all delivered with grace. --Marc Greilsamer
