21th of June is the European Music Day, and hundreds -maybe thousands- of concerts are organized throughout Europe to celebrate it. Polinomio Estudios want to add itself to this celebration by sharing this video of a beautiful Pugnani-Kreisler piece, played by young violinist Maddi Arana in the special concert at Conservatorio de Musica Jesus Guridi of Vitoria -Spain, that took place on that day of 2007.
