[3] In Paris, he befriended members of the young art scene, especially Gilles Aillaud, with whom he later collaborated in creating stage sets, such as Vivre et laisser mourir ou la fin tragique de Marcel Duchamp, a work in eight pieces intended to criticize contemporary French art.
[3] Arroyo 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).
[6] Arroyo's stage play, Bantam, premiered at the Bayerisches Staatsschauspiel (Residenztheater) in Munich with great success in 1986, with his friend, Grüber, as director and Ailland and Antonio Recalcati for sets and costumes.
Exhibiting since 1961, Arroyo's work has been shown in exhibitions across the globe, including the Neue Gesellschaft für Bildende Kunst, Berlin (1971); the Centre Pompidou, Paris (1982); Solomon R. Guggenheim Museum, NY (1984); Museum für Kunst und Kulturgeschichte, Dortmund, (1987); Institut Valencià d'Art Modern, Valencia (1989); Museo Nacional Centro de Arte Reina Sofía, Madrid (1998), and most recently held a solo exhibition at Fundación ENAIRE in Santander, Spain (2021–22).
