Calexico snatch up the bits of Americana turned out by a rototilling of the national music psyche. The 19 resultant tracks can be small as insects (the shortest being half a minute in length) and erratic in flight; there are lo-fi songs and themes that proceed without concern for what came before. One bit is held up by guitar, another by accordion, then one by vibes. A bit of desert dust sprinkled throughout may be the only constant theme — a Santa Fe rummage sale of sounds. Spoke is very intriguing and well worth exploring.
