A student of mine (Noah, a 10th grade aspiring trumpeter) just turned me on to this video. Noah's teacher hipped him to it as an illustration of the relaxed-yet-focused states of the performers. Indeed!
It's a live studio session with Freddie Hubbard as a featured soloist with an A-List LA studio band. Hairstyles and fashion indicates early 1980's. Anyhow, the writing is quite interesting (by screen composer Allyn Ferguson) and the playing is inspiring all around.
