Turrentine's never quite been my cup of tea but with a lineup like that this one definitely deserves a listen.
I am a big Turrentine guy and IMO his best period by far was on CTI. But I like the mid-late BN period stuff as well.
Mr. Natural is something of an outlier. Something shelved at the time raises questions.
First, the band doesn't really gel. On Side 1, Barretto is really out of place. Side 2 is better. No one sounds inspired here. Turrentine's solos are fairly stock Turrentine riffs, and Lee seems to be not the best foil for Turrentine, as Hubbard could be. Elvin's advanced style really doesn't go well with Turrentine's brand of soul-bop.
Perhaps Alfred Lion heard it the same and put the tape on the shelf.
Or, there may be another story. Listening to it, it is possible that Alfred put this together as an experiment, or as a way to break Turrentine out of his mold. Jazz, in 1964, even on BN, was a boiling pot racing ahead. Turrentine was not, and perhaps his sales showed it. Putting this up beside Crescent, Fuschia Swing Song, Page One, or many, many others of that year, seems to me to not show Turrentine as moving the needle at all. Perhaps after listening to the session, Alfred realized this was not the direction to go in. Later records - Easy Walker, The Spoiler - retained Cranshaw and Tyner but brought in Mickey Roker, which was more suitable. Then Common Touch started Turrentine firmly on the soul-jazz/smooth jazz path he would later refine.
So possibly, Mr. Natural was an experiment or attempt that was considered to not be the right direction. To me, it sounds like it. All these players did way better on other records.
A great lineup does not ensure a great record.
I would much rather have The Spoiler or Easy Walker, which were released in the day.
Having said that, I will probably buy it. It is unique to hear Elvin behind Turrentine, even if Elvin's presence doesn't really ignite Turrentine. The original 1964 mix was undoubtedly done quickly for review. Barretto is mixed too much to the front on Side 1, so I hope it has been remixed.
I like the new cover, the Japanese one I never really felt much about.
