Saxophonist Martin Archer composed the five works on this, the 3rd release for Engine Room Favorites, his AACM-influenced big band with a tremendous orchestration of horns with drums, vibes, piano and bass, here with their most complex yet melodic and rich release yet, including melodic elements of folk music, powerful rhythms from prog-oriented rock, and free improv and jazz.
