That only musicians are capable of understanding late period Trane. Frankly, it all seems a little ironic to me.
That statement is slightly incorrect because you stated "Period "Trane", when I was referring to those 3 minutes when he lost McCoy Tyner and Elvin Jones on that set that the professional drummer at the table explained.
Maybe this is the late period "Trane" you are referring to; this is "Trane's" last concert, which you can explain if you care to.

Being a musician, you have the ability to explain this technically, and I'm looking forward to your explanation.
