A very long and fascinating article on Musicweb International by pianist and critic Christopher Howell, in case you haven’t already seen it. You’ll need at least 2 cups of coffee for this one.
UPDATE: Andrys has made an extremely useful page containing all the links anybody could want on this topic. Essential reading and some audio interviews too.
I read the WHOLE thing – Howell’s article is fascinating – a sad story thru emails and letters of what is increasingly looking to be a fraud… unbelievable.
