Maynard Ferguson - nice to listen but don't start by trying to play as high as he does
Wynton Marsalis - if you want to incorporate effects in your impro he is the man...one of the most inventive improvisers I have ever heard...some peolpe on TM may disagree, so that's MY OPINION. Reactions of other players can be quite different on what he does...yet Nobody can deny that he is an awesome musician
Harry James - Great sound...I wonder how he get missed in this list
Are non-trumpet players allowed? I guess they are
Al Jarreau and Bobby McFerrin
