Carefully picking and collecting, meticulously arranging and rearranging, meaningfully quoting and commenting: this is how Luciano Berio looked at composition. In Naturale, the raw voice of a Sicilian folk singer crosses the polished folk songs of the viola. A virtual love duet from his opera 'Cronaca del luogo' is given a completely new context in Altra voce for voice, flute and live electronics. Jumbled fragments of text hesitantly find their way to an understandable order in the tribute O (Martin Luther) King. Berio refreshingly colored his own and other people's work - from Monteverdi to the Beatles - with his personal touch. In the same way, six international composers tackle his Six encores for solo piano, as a tribute.
