The piece, located inside the subway station of Paco de Lucía, is entitled "Between two universes", in homage to the brilliant Spanish guitarist and composer and in reference to his song "Entre dos aguas" (Between two waters). Two universes converge in the mural: on the left, that of Rosh333, who has captured his characteristic language of curved lines, textures, sinuous shapes and spots of pastel colours; on the right, that of Okuda, who has done the same through his geometric figures, starry shapes and vibrant colours. Both universes merge in the central area with a portrait of Paco de Lucía, painted by the two artists.
