On Christmas Eve 1950, the Italian Radio broadcast a radio play based on Adalbert Stifter's novella Rock Crystal. The music was written by Nino Rota, the translation was made by Gabriella Benci and Ippolito Pizzetti (the son of the composer Ildebrando Pizzetti, one of Rota's teachers). Here, too, the duo carefully edited the existing piano version. With these two pieces, the piano duet repertoire has taken on a whole new colour, and both performers and listeners can plunge into the atmosphere of Rota's film music.
