"We can start with the celestial heights of Casals and Serkin. These discs were made at the Prades Festival concerts in 1952 and 1953, and now and then you will hear the great man Casals grunt as he attacks a phrase. Casals was 76 in 1952, and his bow arm was in less than perfect control but this performance is classic."
-– Herbert Russcol, WQXR, 1969

"Humane and wonderfully wise…a revelation of warm, human, profound interpretation."
-– Edward Sackville-West (1901–1965), novelist and music critic

"Excellent both tonally and in matters of balance. Two perfectly matched musicians operate here. For every bold stroke of the Casals bow there is an equivalently authoritative gesture from Serkin."
-– Harold Schoenberg, (1915 – 2003) author and New York Times music critic
