Well, the article is a tie-in to a concert series honoring him, and the thrust of the article is his legacy, so it seems perfectly natural that he'd write about those other pianists. And he quotes those other pianists talking about Cecil, so I don't understand what the problem is.
Though the fact that he has female assistants lighting his cigarettes and bringing him champagne makes me lose a bit of respect for him, and I do find his extra-pianistic performance antics rather silly and annoying.
