Here is an interesting artist that's new to me, and I wanted to share his music.

***** You must be hung up on European heritage.*****

I make be hung up on many things, European heritage ain't one of them.

The correct answer is the piano.   It is more expressive than trumpet or sax.   I have never seen anyone, save classical players, play trumpet or sax on stage by themselves.   Those instruments are not expressive enough by themselves.  They need support.   Remember, we are speaking of Jazz.

Cheers

You're just plain wrong, and I can tell our disagreement will never be resolved.
Keep in mind - Louis Armstrong was inspired not by piano, but by the rags bottles and bones guy playing his heart out on a tin horn.
King Oliver, Buddy Bolden, Louis... the roots of jazz aren't traced to piano.

Louis Armstrong, Charley Parker, and Dizzy Gillespie, are three of the most renowned names in jazz; two trumpets and one sax, no piano.

We hear of "Concert pianists", but that's in another Genre of music. I like long piano solos, but that's as far as it goes. A solo piano all night long grates on my ears; eventually they begin to sound like "Schroeder"; that's the kid with the toy piano in Peanuts.

Your ears are specially tuned to pianos, which is why you like them so much. My ears are more tuned to sax and trumpet. That being said, I wouldn't even want to hear a solo sax or trumpet all night long, no matter who played it.

It just boils down to; "Different strokes for different folks".
