Query: Pau Casals, the great maestro!!!

This is one of the best things I have ever heard in my whole life! The great Casals performing Brahm's concerti. Maestro Pau Casals ( 1876-1973 ) was, certainly, the best musician in the twentieth century. He was, also, an incredible conductor, and a composer, too ( for example " El Pessebre").However, in this cd, we are able to hear Mtro. Casals playing his violoncello sharing the orchestra with some of the best musicians, the french pianist and conductor: Alfred Cortot and the pianist Mieczislaw Horszovsky. This is a very interesting jewl because Cortot is conducting which is not common in the recordings. This Brahm's performance is beyond our undertsanding inasmuch as the musicians are the best ones in the history. When you hear this record, you will agree. I do not write down a lot because I think the names in this cd are more than sufficient.
