Allen, I largely don't deal with those particular intersections. On the good advice of my editor, I resisted the urge to try for complete coverage and so consequently had to make some decisions as to what could be pared. As there's already lots of good scholarship on the kinds of topics (and the period) you mention, I wanted to focus thematically on not just religious traditions, but ritual, communitarianism, cosmology, etc. My goal was twofold: to argue for the seriousness of jazz as a subject of reflection in Religious Studies (my discipline) and to complicate/broaden the discussion of "religion" or "spirituality" in Jazz Studies.
Jim, cool anecdote.
Thanks for the interest, all!
