Desc: a3520 for Piano Solo: Directed by Tony De Nonno. With Matthias Kreisberg. In a3520 FOR PIANO SOLO: a film by Tony De Nonno you will experience Matthias Kriesberg performing his piano composition "a3520," a work The New Yorker called "exhilarating," in the dark resonant interior of a 19th century Gothic cathedral in New York City, see the dynamic images award-winning filmmaker Tony De Nonno has created to move in harmony with the composition. Matthias Kriesberg, one of the leading composers of his generation, treats piano in startling new ways keeping the entire keyboard in motion at once. De Nonno's lyrical camera angles and dramatic lighting creates an atmosphere in sync with the explosive psychological power and subtlety of Kriesberg's "new tonality." This contemporary music video offers insight into a new performance technique and aesthetic vision that will inspire composers and performers in their own personal expression.
