Someone who has given me very valuable feedback on my site once mentioned how David Oistrakh, in his opinion, was the greatest violinist. Here are a few works by him.
Brahms – Sonata for violin and piano no. 3 in D minor / Adagio
How playful Beethoven can be!
Beethoven-Serenade For Flute, VIolin And Alto In D Major-I-entrata-Allegro
Debussy – Prelude ‘la Fille Aux Cheveux
