Well, ok - what is a "rap" (as in "bad rap") if not a collection of opinions about his playing? Good rap, bad rap, whatever, there's nothing more to that than opinions. It's not like he's been inaccurately characterized as a junkie or a wife-heater, it not that kind of a bad rap.
But here's that kind of a good rap!
AFAIC, I got more time for this than I do for Oscar Peterson, especially today. . After all, everybody's rappin' - and only few can flow.
And no matter what you're talking about, that is truth.
