He is so taken with his idea of his own 'genius' that his improvisations tend to be monumentally self indulgent, and what is worse, self aggrandizing. I find that he never really invents, but merely elaborates, which is different. Overly and artificially 'dramatic', dynamically forced, and saturated with a sense of 'here it comes people, listen to ME'. I personally cannot stand his music even though he was a great side man. His solo recordings nauseate me.
