In 1970, Pink Floyd composed "Echoes", a long track, released on their 1971 album "Meddle". "Echoing" in my childhood memory , this song was the starting point for the creation of this piece: a kind of algorithmic musical code, geometrically progressing from the center, on a pink background. The search for a new and original technique and language for digital pictorial representation takes on a minimalist modality here. The division of the composition and the subtle balance of "masses" corresponds, once again, to the attempt to represent musical "harmony".
