Here is a little gem. In many respects. A wonderful piece. Extraordinary artists. Add the two and you get a great musical moment. The piece: Sonata in A minor for Cello and Piano, Op. 36, written by Edvard Grieg. The artists: Françoise Groben playing the cello and Alfredo Perl at the piano. Perl is a Chilean-German pianist and conductor, known for his Beethoven interpretations. Mrs. Groben was a Luxembourg cellist, no, she was THE Luxembourg cellist.
