Pablo (Pau) Casals, interpreting J.S. Bach in Abbaye Saint-Michel de Cuxa, France, 1954
Bach Cello Solo Nr.1, BWV 1007
I remember playing the original LP (or an EMI copy thereof) long ago on the radio. As the YouTube publisher states, those versions are superior to this recording. But hey, this is apparently the first video of Casals’ performance. I’ve lost count of the number of times I’ve passed it on here on the Internet; it is a long-time favorite.
