The film that gave Pam Grier her first leading role and vaulted her to queen bee of the blaxploitation movement also inspired a soundtrack that is arguably Roy Ayers's most rewarding work. Grier plays a disgruntled nurse who goes "underground" to exact revenge on the pusher men who put the monkey on her junkie sister's back. Ayers matches her step for gun-totin' step with crisp, percolating drum lines; colorful ripples of electric piano; and his signature, lissome vibe work. Ayers' twin talents--the head-scratching virtuosity of his jazz runs and the ass-shaking grooves of his R&B rhythms--are in full flower on this recording. But Coffy is more than an acid-jazz archetype. The classically inspired solo harpsichord piece and the wack auxiliary percussion freak-out also included here hint at a deeper pool of inspiration that Ayers would rarely return to again.
