Right you are sfar, Ry and Flaco have worked together a lot.
infection, Van Vliet was, as expected, like no one else I've ever seen. Said not a word to the audience! His vocals were very low-pitched, and his band played very economically, leaving much more space than most. Like Jazz players---very deliberate phrasing, notes played to achieve a desired effect, not just played to be playing something, like most Rock players. The whole thing was rather cerebral, directed at the intellect, not the heart or testosterone ;-).
