The editions by the Bärenreiter Verlag have accompanied me all my life. Undoubtedly the most important connection (so far!) however has been the wonderful collaboration between Barbara Scheuch-Vötterle, Leonhard Scheuch and Dieter Ammann in the creation of one of the greatest piano concertos of the 21st century.
