Few 21st-century musicians make US roots music that's exciting and edgy. Califone rank as the most interesting group working in this overcrowded field. Arising from the remains of soulful blues-rockers Red Red Meat, Califone extrapolate RRM's yearning, spindly sound into more adventurous, orchestrated realms. Leader Tim Rutili's an eccentric soul singer, his slurred drawl conveying an ache that helps make his band's askew blues sound both ancient and fresh. Califone harvest an Americana that's all wheat and no chaff. Buy tickets here. (Crocodile, 2200 Second Ave, www.thecrocodile.com, 8 pm, $12, 21+)
