Josè Daniel Cirigliano, who is considered 'one of the best contemporary clarinettists' (Roberto Zecchini, in 'Musica', May 2015, no. 84), after the CD Opere Contemporanee per Clarinetto, offers us a new, stimulating excursus in the contemporary music for solo clarinet of the last few decades. Within this CD we see various twentieth-century composers challenging clarinettists and pushing the boundaries of the clarinet: from William Overton Smith, winner of the 'Grand Prix de Rome' in 1957, to the young Roman Alessandra Ravera, through figures by the great personality such as Giacinto Scelsi, or masters who left their mark like Bruno Bettinelli, or specialists of the clarinet technique like Antonio Fraioli and Giovanni Mattaliano.
