"Why this wave of emotion and excitement? Some attributed it to a great publicity build-up, and one writer objected to the use of the phrase, 'The Pianist of the Century'. 'Which century?' he asked. This was the same critic who labelled Horowitz on his debut as 'the greatest pianist, living or dead'. It is obvious that Richter's gramophone records were his best publicity agent, for these fine recordings have been available for some time and they have so impressed the discerning listener that the message has been passed round-'Here is a great pianist'. Publicity has not suppressed judgment here."
