Ayers was definitely a vibes man to look out for when this was made, of course not long after he made a 'move for the groove' and became a funk-smoothy. (That his producer was Herbie Mann may explain this to some extent). A piece of info: the pianist (Herbie Hancock) under a pseudonym, is virtually inaudible - perhaps this was because he was under contract elsewhere. That does not explain why Harold Land is inaudible on the one track on which he appears. The jacket gets it wrong in saying that Side One (tracks 1-3) is by one band and Side Two (tracks 4-5) is by the other. Only track 5 has the band with Land. Also, the bass work on both sessions is also near subsonic. These are the reasons its a 4 star review. Otherwise we have great playing by all concerned, Charles Tolliver especially - why didn't we rave about him then? Joe Henderson is masterful if not to my taste so much. The rhythm sections are equally fine. This is accomplished post-bop jazz with no frills and no attempt at being 'pop'.
