Live recording of the piano recital for the eightieth birthday of composer Hans Otte that Philipp Vandré and Elmar Schrammel presented at the Akademie Schloss Solitude in Stuttgart. A selection of John Cage's "Sonatas and Interludes" for prepared piano was interwoven with selections from Hans Otte's piano cycles "Das Buch der Klänge" (The book of sounds) and "Stundenbuch" (Book of hours). This concert experiment, conceived by Ingo Ahmels, paid quiet homage to the "beautiful piano sound" also found in twentieth-century music, within which Occidental (Otte) and Oriental (Cage) worlds of thought find their way to contrasting commonalities.
