Many years ago I read an article that analysed Lester Young's solo on the Jones-Smith Inc recording of "Shoe Shine Boy." (Jones-Smith was a pseudonym for the Count Basie band and this was, maybe, their first recording.)
One of the points made was that right off in the solo, Young performs a couple of really difficult moves as if to say: "Here I am, move over. Now listen here."
Piano players have the same stuff--scale and arpeggios done really fast. So do organists. Guitar players, of course, have little else (wink smiley here).
What, think you, constitutes a bragging rights lick on synth? It's such a very different instrument than piano or organ, I don't know if there's an equivalent.
Lester Young's solo starts at 0:44 after Basie's piano.
