'I often played Berio's Erdenklavier in my childhood, which is why I wrote this short epigram to take leave of the Maestro and Friend who is playing on a Himmelklavier now. From 1979 I worked many times with Berio in IRCAM and in several festivals in Italy which were led by Berio. I regularly conduct all his symphonic and ensemble pieces''. I remember our last cigar-smoked dinner with him in 2002, in Rome, when he invited us with Pierre-Laurent Aimard for concerts with Santa Cecilia. '' (Peter Eötvös)
