Sensational Spanish violinist María Dueñas is the latest winner of the Menuhin Competition, the world’s most prestigious prize for young violinists. Born in Granada and now based in Vienna, Dueñas is one of the most thoughtful and communicative musicians on the current classical scene. Her second e-single is out now: Espérance (“Hope”), the first of the Two Impromptus, Op. 4 by French composer Lalo, the 200th anniversary of whose birth is being celebrated this year.
