Herbie Mann is on this, uncredited for contractual reasons. He was allowed to record one album in two years on other labels than Atlantic, but did more, of course. There`s a note found on discogs: " The identity of "The Fluteman" remains in question. While Herbie Mann has confirmed to researcher Dan Skea that he appears on this record, producer Creed Taylor has also informed this researcher that Hubert Laws is the mysterious flautist. Given the aural evidence, it is possible that both appear under this title." And I wonder if that "Henry Watts" credited for playing vibes actually was Roy Ayers - no other recordings by that guy to be found.
This and Herbie's A & M LP would have made a nice twofer CD.
