My mom had the Casals LPs when I was young, and would sometimes play them as I went to sleep at night. The audio wasn’t nearly as good as some of the other versions, even in the 1970s, and I think he plays them quite a bit more slowly than Rostropovitch, Ma, Kremer, and the others I’ve listened to. Still, there’s something special about the Casals recordings. For one thing, he was the one who “discovered” a manuscript in a thrift shop. You can read more about the Suites at the Wikipedia entry.
And you can take a Master class from Sr Pablo here!
Beautiful, thanks.
