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 have to get back to writing about other things today: a top singer, an innovative chamber ensemble and teaching organisation and five CDs for review require urgent attention, plus I've got a friend coming round to play through a violin concerto tonight (with piano, not orchestra) (with a real pianist).
