I am just listening to the youtube clip

he actually starts with the same notes of his solo on the Blue Train album.
It sounds to me he stays on Eb7 (concert) blues for a while. But I don't understand McCoy Tyner's chords. It sounds like he is thinking C minor, but I am just on my laptop.
Dolphy, on the other hand, is playing in his own personal tonal system 🙂
Thanks for pointing it to me.
