For me this CD represents a closing of all the Jazz that came before it, since it was released in the era between Free Jazz and Fusion. It is post-everything music, containing elements of modalism, hard bop, free music and hard swing. Although Lee Morgan's name is on the cover it is most certainly a group effort; the songwriting was contributed by nearly all of the band-members, with Morgan himself providing only 2 of the 12 titles! There is no hogging the spotlight, just strong solos and incredible group interplay. This re-issue should have done more for the reputation of reedman Bennie Maupin, who creates perhaps the best and widest ranging solos of his career. Although the tunes range from 11 to 22 minutes there is no flab here and no wasted solos, just strong musicianship all around. It would have been interesting to see just what Morgan would have created after this had his life not been cut short. This is truly timeless music.
