I remember hearing a story about Art Blakey being with a very young band of his in the studio. It was not going well because the young players were nervous, and he told them "If you play a wrong note, play it loud, and then play it again, and they'll think that's what you meant to play". And I saw Javon Jackson spend a whole show with the Harper Brothers (Penn's Landing in Philly, circa 1989) where he seemed to be doing exactly that.
