The most thoroughly realized blueprint for a post-hardcore take on improvised jazz to date from the duo of legendarily long-serving New England saxophonist Paul Flaherty and young firebrand drummer Chris Corsano. Forsaking the call and response modes of countless improvising ensembles, the duo deal more in a simultaneity of sound, an elemental non-stop gush of ideas, rhythms and epiglottal forms that at points feels like a small-group response to the orchestral conceptions of the Peter Brotzmann and John Coltrane big-bands as much as epochal duo deals like the Rashied Ali/Frank Lowe and Muhammad Ali/Frank Wright sides.
