"Richter magnetized me, like he did so many others, and I wouldn't have missed his concerts for anything. I think he communicated more than anyone else complete devotion and sincerity to his art. When I look back, this is what attracted me most to him then, and continues to do so today. I now understand that the strongest element in his magnetic appeal to audiences is his conviction that what he does is absolutely right at that particular moment. It comes from the fact that he has created his own inner world, absolutely complete in his mind, and if you argue with him about anything it's almost no use. He might say "Yes, perhaps you're right, but I just don't feel it that way. This is what I feel and this is the way I play." And that's it. I don't often agree him after the performance, but during it I can see that everything fits together and is completely sincere and devoted, and that wins me over. I'm sure that many people feel exactly the same but, in my case, since I am a practising musician, the fact that I am won over at the time of the performance is extraordinary. In almost all other cases I disagree right there and then at the moment when a performance is taking place! In addition to his many other wonderful qualities Richter is for me the greatest interpreter of Debussy; his playing really has three or four dimensions. It's not just beautiful sounds and beautiful sonorities; I find the imagination behind the sonorities unmatchable. There is a fantastic feeling of spontaneity and of "creating at this moment". In fact, everything is worked out before, but at the same time he always creates "at this moment", and this feeling is marvellous."
