A beautiful example of the maturation of American avant jazz in the 70s – a set that has the Revolutionary Ensemble really drawing their sound into focus, drawing on older experimental modes and forging them into a rich new vision – one that would certainly live up to the AACM's promise of "Great Black Music"! The tracks here are all quite long, but they also have a careful, thoughtful feel too – not just improvisations, but measured exercises in spirit and sound – played beautifully by the trio formation of Sirone on flute and bass, Jerome cooper
on drums, percussion, and balaphone, and Leroy Jenkins on violin, flute, and kalimba! The mixture of instrumentation is handled with Art Ensemble-like precision at points – never academic, and occasionally loose enough to be loft jazz – but always with an ear for organic richness of sound, in ways that make the album a surprising delight at each new turn. Titles include "Chicago", "March 4 1", "Clear Spring", and "Revolutionary Ensemble".
