Query: Pretentious

Dear Mr. Marsalis,You badly need a lesson in learning to make sincere and warm music. You are a product of the establishment. You are so obsessed with grandstanding projects that you continue to overlook the fundamentals. It has probably made you finaicially wealthy but musically depraved.Please please please take lessons from Terence Blanchard, Roy Hargrove, Marcus Printup or even Christian Scott to name a few. Talk less and listen and practise more.I have not forgotten your scurillous remarks in the 1980s of the late Miles Davis's foray into modern electronic pop jazz. It was naive and ignorant. If it was not for Mr. Miles, you would not have found your opportunity to blow your horn(for want of a better expression). Your recent recording shows that you have not changed.
