The vast realm of “spiritual jazz” can also be called jazz in the wake of the Coltranes, or maybe post-Ayler, all of which is to say it is the sense of an invocation that comes into play here. I’m not sure there is non-spiritual jazz—who hasn’t felt the presence of God when listening to Bird or Monk?—but sure there is a big chunk of important music that came into being that borrows a sense of procedure from Coltrane, a primarily spiritual musician. The Carns lead with electric piano and voice, and fill it in with sensitive arrangements that surge and fall back and find a way of containing freedom without stifling it.
