Details: The two concertante pieces and the two large triptychs gathered here testify to César Franck's dazzling maturity in the last years of life, as well as to his return to writing for the piano. The quintessence of his creative quest is manifested in these formally ambitious, expressively powerful, harmonically rich and architecturally masterful works. Above all, they affirm the genius of this incomparable mind, constantly driven by a thirst for the absolute, of which the music is the sublime reflection, between torment and consolation, between passion and spirituality.
