If I dared, without fear of cliché, I would write "It's magic". It's written, and I assume it's true, but beyond the convenient formula that allows you to try and express the unspeakable, it's simply the expression of an obvious fact: in this encounter, there happens what sometimes (as often as possible!), improvisation without a net produces musical happiness, as immediate as it is resistant to the analysis of multiple listenings. A truly great moment of improvised music!
