Oscar Peterson vs. Art Tatum

Mosaic recently released a compilation of CDs entitled The Classic Oscar Peterson Trio Studio Sessions With Ray Brown and Ed Thigpen.  In the opening notes Bob Blumenthal correctly writes that Peterson had "technique and harmonic fluidity to rival Art Tatum" and yet that fact has troubled me for years.  Everything the trio played was well rehearsed.  Nothing was left to chance.  Anyone who ever went to hear the group live commented on how they played the same tunes, the same riffs, same everything night after night.  This was a well staged act.  I heard Stanley Turrentine in Chicago years ago and he covered some Coltrane things.  It was uncanny and when I spoke with him he said "Oh yes, once someone shows me how to play a piece, I can play just about anything.  The difference is that John can stand up there and think that shit up as he goes along.  The difference between true genius and the rest of us mere mortals."  And that is the difference between Oscar Peterson and Art Tatum.  Don't get me wrong, Peterson is terrific and this set is well worth hearing.  In my youth I wanted to be a drummer and learned to play brushes from Ed Thigpen.  Wonderful stuff.  Truly.  Just keep it all in perspective.  With total respect for everyone involved including Bob Blumenthal, who I grew up reading while I was a student at Berklee, when it comes to INVENTIVENESS, harmonic and otherwise, there is Art Tatum without equal.  Oscar Peterson definitely had the chops, but he could not think that shit up as he went along.  It has only taken me 60 years to figure this out, but then I am also a mere mortal.
