New jazz pioneers Henry Grimes and Andrew Cyrille are creating a holy mess of sound right now, totally improvised and bad ass. "We'll call this one 'The Perfect Thing'" Grimes says beforehand. This must be a whole other kind of perfect, then: they come dangerously close to cacophony, before folding in eastern rhythms and polyphonic textures that shimmer and glow; when Grimes switches from bass to violin, he almost sounds tonal Almost. I can't even begin to understand how these guys know what to do when, there are so many ideas flying around here. When you've been doing this stuff for fifty years, though, it's probably easier than breathing.
