"Accident Happening" and "Ground" feature stormy "outside" playing (think Roscoe Mitchell, John Zorn) yet are possessed with unsentimental passion and urgency. With INCLINE, Vandermark deserves to be up-there as one of THE modern jazz composers (i.e. Geo. Russell, Carla Bley, Henry Threadgill). Highly recommended for adventurous jazz (and rock) fans who crave audacious sounds that do not sacrifice accessibility and directness.
