Maybe we should retitle this thread "Musical Experiences that changed your life".
The Emerson solo on "Blues Variation" was an high point for me too. Also, when I heard the Weather Report live for the first time, I was stunned by the fact (among many other things) that Zawinul played the closing keyboard solo on "Birland" exactly like on the record, keeping the riff chords in strict rhythm with the other hand, and at the speed of light. I was like, "wow... it's impossible!"
And being a jazzer at heart, I remember quite a few really devastating solos, both live and from records.
But if you ask me (you asked, didn't you?) the most revealing music experiences of my whole life, I can only think of two, and only one is keyboard-related.
OK, watch for my English!
When I was about 13, one of my music teachers, a lady, told me: "Rudolf Serkin is about to come to Rome, you should go - and learn." I wasn't that enthusiast (I never heard of him), so she called me again: "I got tickets. Let's go - you won't regret it."
Serkin played some of the last Beethoven sonatas, op. 106, 110 and 111, I believe. He was quite old already.
Well, from the first note I was drawn into a new world. Technique? Yeah, he had technique to spare of course. But technique was the last thing I was thinking about! It seemed to me that he could think of the deepest meaning of every phrase with absolute identification, and then "tell" the piano to play like that. It seemed not only magical, but effortless. I'll never forget that night.
About 20 years later, one summer evening I went to see an outdoor show featuring the Ivory Coast National Ballet. Three Musicians (all drummers) and about five dancers.
Well, the dances were wonderful, and the dancers themselves were so beautiful that you would look at them even if they didn't move. The costumes too, really a joy.
And after I while, I stopped completely to watch the dance, and gave my total attention to the music of the drummers. Those guys were playing a symphony of rhythm, a counterpoint more complex than any Bach double fugue, with *incredible* dynamic control and rhythmic elasticity.
Tempos an signatures constantly changed, shifted, stopped, added, regenerated, all with absolute and *natural* flow and togetherness.
I thought, "we really don't know anything about rhythm.... they are the masters."
I still think so.
