I like it a lot. Although the packaging would indicate that this is another session led off by a formula funky boogaloo, it's actually is a fine session with a few players not commonly heard on Blue Note dates, because it was recorded in Paris. When this originally came out, I passed on it after having been a little disappointed in its predecessors, Hi Voltage & A Caddy For Daddy. Eventually I caught up with it, and in my opinion, this album is better than either of those.
I wouldn't say that it's especially hard to come by, certainly not among the rarest Hanks, probably because it came out during the Liberty era.
