If JJ Cale is influencing a new generation (see M. Ward's country blues rock and Jenny Lewis' name-checks) maybe it's because, at 70, he's a model for indie-rock longevity. On his 16th record, the Oklahoma-born singer-songwriter-producer sticks to his low-key DIY guns, notwithstanding cameos from pal Eric Clapton and others. The songs are top-shelf: Most ride Cale's signature shuffle groove and are delivered in his barroom Zen-master growl while his bubbling guitar — as much a jam-band archetype as Jerry Garcia's — glints across the shadows. Supremely chill, utterly ageless, Cale's style fits him as perfectly as it did three decades ago.
