This is a novel document based on commitment and solidarity. Its most perceptive protagonist is the young pianist Luis González Lladó who, guided by the desire to be coherent with his time, proposed to a heterogeneous group of Spanish, Portuguese and Latin American composers the creation of a nucleus of piano works based on the formal model of the prelude, freely reflecting their conception of the aesthetic time in which they were immersed. That proposal formulated in 2017 fostered a significant collective response, to which this phonographic document aims to attest in the first instance with the works and authors selected by the pianist Luis González Lladó himself. The free creative expression and the unique technical and stylistic design that each author has stamped on his work are formulated as paradigms of the created fact, the pianist being the authentic interpreter of its contents and assuming responsibly the profiles that all interpretation implies as a recreating fact. It is the composers themselves who describe their works, all of which are dedicated to the pianist who performs them.
