I really don´t understand your answer, Elvin, Blakey , Kruppa and Buddy didn´t went to Jazz University, so they don´t have any relation with the movie wich is about JAZZ at University (????)
my answer is sayign that the greats, probably for the most part, did not go through the process that the movie is trying to convince people of to become great, regardless of whether they went to university or not. Whiplash totally rienforces the notion that to get better, drummers just bash, "play until their hands bleed", only work on speed, and are outright jerks to each other. In any drumming community, that is just not the truth any more. But now, becasue of the movie, there are masses of people who think that that is what you need to do to become a great drummer. That sucks....
and I didn't view thaty movie as singularly about drumming at a university, but more about one guys expereince with trying to get better at drums. It happened at a university, but I think there are some bigger picture things going on there
