He is a Spanish painter and graphic artist. He was born in Madrid on February 26, 1937. He studied art there, then left Spain in 1958.
In Paris, he befriended members of the young art scene, especially Gilles Aillaud, with whom he later collaborated in creating stage sets, but also the old master, Joan Miró. In 1964, he made his breakthrough with his first important exhibition.
Stylistically, Arroyo's mostly ironic, colorful works are at the crossroads between the trends of nouvelle figuration or figuration narrative and pop art. A characteristic of his representations is the general absence of spatial depth and the flattening of perspective.
Arroyo also became known to a broad public through his many works as a set designer, as well as partially by his costume designs. In this relation, he has cooperated since 1969 especially with the director Klaus Michael Grüber, who has encouraged him in this activity. Arroyo has created sets for, among others, the Piccolo Teatro in Milan, the Paris Opéra (in 1976, Richard Wagner's Die Walküre), the Schaubühne am Lehniner Platz in Berlin and the Salzburger Festspiele (in 1991, Leoš Janáček's Z mrtveho domu).
Today, the ideologically and passionated artist is still very active.
