This surpasses, in both content and approach, most of the undergraduate music theory courses that I had in college. Phenomenal crafting and analysis.

Your Duane/Fillmore East anecdotal tie-in gave me shivers. I've always felt that Live at the Fillmore East has several lifetimes worth of musical beauty and inventiveness.

Having said all that, I haven't 'revisited' Wingsuit since I witnessed the debut from the couch, but if left feeling as optimistic about the near future of this band as I have in many years. I don't think this level of inter-song points of interest (as it relates to key, harmony, melody, tension, reprise, etc) has been a part of a studio release since 'Billy Breathes'. My expectations are high at this point.
