I tend to like jazz that leans more latin, like Chuck Mangione or Arturo Sandoval. They’re both typically a little more upbeat than the example you gave, but of the two Mangione is definitely chiller than Sandoval, some of Sandoval’s stuff gets pretty frenetic.
The Flugelhorn is such a beautiful instrument! I almost had a chance to play a solo on one in my high school marching band, but the first chair trumpet stole it from me, lol.
