The Justin Hurwitz's soundtrack from the movie Whiplash (one of the greatest) directed by Damien Chazelle. 
Remember this tune ? It was recorded in the jazz club where Neeman met Fletcher before his last gig (where the latter gave the wrong part, on purpose) at the end of the movie.

Enjoy listening this very smooth like version of it ! 
By the Sons of Smooth, Strasbourg, France.
