À Claude stems from a profound admiration for Claude Debussy and his legacy, a composer who thanks to his intense aesthetic, formal and timbral research has been a fundamental pillar and turning point for the 20th century's musical production. The pro-gramme aims to be a family reunion, an ancestral tree starting with Claude Debussy and branching out into all the subsequent generations: Olivier Messiaen continued Debussy's research, merging it with his personal interest in colour and non-European cultures; the Japanese Toru Takemitsu who pays homage to Olivier Messiaen and his rich harmonies; the American George Crumb, whose work takes the piano towards unheard-of timbres and considers Claude Debussy his greatest teacher; the Roma-nian Diana Rotaru, who pays tribute to the two great masters with her Debumessquisse and finally Benedetto Boccuzzi attempting to condense this legacy in his short piano piece (quasi) Notturno.
