==This article needs work==  
 While there is no doubt this artist is notable and the article should be here, I have the feeling that it was pieced together from foreign-language sources, old photocopied articles and the artist's own manifesto(s). It seems that the main things to do are to: 
 * provide sources other than Barrio's own text for the many many claims that are made about his practice,  
 * find sources for his actual nationality, as many are listed in the article... 
 * reduce the hype-laden text on the significance of his work into something more encyclopedic, and 
 * provide some easy to understand text on what he is really famous for: using disgusting things like blood and the like as art materials, and what this meant as a challenge to more formal art practices.
