Kinderszenen is an interesting collection. I think that people often assume that it's music for kids (i.e. beginners), but it's really music about kids. The music is much more complex interpretively than most people realize. I've got a great video clip of a fairly old Cortot playing the last piece of the collection ('The Poet Speaks'). He appears a million miles away as he plays, plumbing depths that most of us don't even realize exist. This performance transformed the way I look at the collection.
