Why Does All Jazz Sound The Same?

OP-- it's unclear whether we ought to take your post seriously or regard it as an attempt at humor... or is this ambiguity precisely what you intend? 

Punctured ear drums?

@snackeyp, 
I'm not sure what you're listening to. Listen to the following small sample.


Piano,  Theloneus Monk vs Oscar Peterson.
Guitar,  Wes Montgomery vs Jim Hall.
Trumpet,   Clfford Brown vs Chet Baker. 
Alto saxophone,  Paul Desmond vs Charlie Parker. 

If you're unable t distinguish differences between these iconic jazz musicians playing the same instrument then something's wrong.
