In Pablo Casals' as-told-to book, "Joys and Sorrows" (1970), there are two photographs on p. 192 that show Casals listening to an LP recording, with the associated quote "Only recently I was listening to one of Sarasate's old records, made at the turn of the century. . . . What an extraordinary virtuoso he was!"
The record player is a very ordinary KLH-type 1960s portable phonograph, the kind that looks like a Samsonite suitcase when it's shut up.
That Casals would have chosen to hear his great heroes of the musical past on such a mundane instrument made quite an impression on me when I read it years ago.
