@mahgister I like so much Paul Desmond with Jim Hall ...
Paul Desmond has the most distinctive tone on the alto then any other. Every solo is a thing of beauty...
What do you mean by "showing off"? Back when Be Bop turned the swing era of jazz upside down the late night jamming sessions in all of the NYC nightclubs and cafes were attended by anyone who wanted to and was not afraid to compete... It was aright of passage when your "chops" and virtuosity were accepted by your peers and you became "one of them" There was no publicity - just the artists jamming.....
These jamming sessions would start at closing time around 4am and continue many times until 10am....
Norman Granz became very well known by hosting "jam sessions" for the public and recorded (thankfully) many of them. Granz called these jam concerts Jazz At The Philharmonic - JATP. Most of the recordings are sub par sonically but are still exciting to listen to.
All of these musicians could play a song beautifully from ballads to blues and waltzes....This is one of my desert island sessions
