Apparently the "Hatto" recordings have been traced to 66 different pianists. (Details are at Farhan Malik's site.) Rod Williams, the author of the Intelligent Life article, has tracked the literature about Hatto and found that some unsubstantiated claims had been made over the years about her training and early career. What a surprise, eh?
I'm especially intrigued by this:
James Inverne, editor of Gramophone magazine, was contacted by two critics who wished to remain anonymous, to warn him off this story.I wonder if those particular critics would be willing to come forward now.
Update, Sept. 11: Mark Singer's New Yorker article is now on line and a must-read.
