What I particularly admire in him is the firm stand he has taken, not only against the oppressors of his countrymen, but also against those opportunists who are always ready to compromise with the Devil. He perceives very clearly that the world is in greater peril from those who tolerate or encourage evil than from those who actually commit it.
Albert Einstein's tribute to Casals (30 March 1953), in Conversations with Casals (1957), by Josep Maria Corredor, translated from Conversations avec Pablo Casals : souvenirs et opinions d'un musicien (1955).
His playing . . . is one of those rare things that may only come once in a lifetime and even not in one person's life, it may be centuries before there is anyone like that again. He is a funny little fellow only about 30 and plays with his eyes shut practically the whole time, every note every pause and tone colour is reflected in his face and to hear him again, to draw the bow across is a revelation.Pablo Casals
The most perfect technique is that which is not noticed at all.Pablo Casals
