In his biography of Ben Webster, Frank Büchman-Møller is very dismissive of that disc, qualifying it as "(...)- with the exception of a couple of musical highlights- a disappointment, as neither soloist played up to par, and the rhythm section consisting of Tete Montoliu, Peter Trunk and Al Heath never merge as hoped". Then, Büchman-Møller states that the album demostrates how differently the two saxophonists had developed from the same background, with Coleman Hawkins as the primary reference. I cannot concur with the first statement, of course. 

Some 25 years ago, I was very reluctant to deep dive in Keith Jarrett's discography, maybe constrained by his "persona". I see things very differently today. And this disc is a beauty. 

I've been trying the Ludos wired.  They sound fine, but fall out of my ear when I move my head. https://www.amazon.com/dp/B0DP972MV7
