Andre Previn is a good all rounder i,e Pianist and classical conductor I really have nothing against him.I must now try to find another questionable jazz person and I would like to present Andre Previn for
comment.
In small group jazz a "Drummer????" that uses sticks is a buffoon.
I get what you mean Mike , but I think the example here from Youtube falls into your category - "Is it jazz?"

But what about Wynton Marsalis - is the following stuff jazz, or is it just noise on a trumpet?
