This is a prime example of collective improvisation without a roadmap, executed by a group of kindred spirits and like-minded daredevils who thrive on the extreme edge. With a core group consisting of Atlanta renegades and Aquarium Rescue Unit, Allman Bros. alumni and current guitarist of "The Dead" and "Phil Lesh and Friends," Jimmy Herring, bassist Ricky Keller and drummer Jeff Sipe (Susan Tedeschi, Jonas Hellborg), this edition of Project Z is augmented by keyboardist Jason Crosby (Robert Randolph) and alto saxophonist Greg Osby (M-Base co-founder and talent scout for Blue Note Records). They play it strictly in-the-moment with a no-holds-barred approach that shifts from boppish swing to slash 'n burn, from dense noise-thrash freakouts to fragile, zen-like moments of silence.
