Kati Krause wrote in the Wall Street Journal:"Sergio Hidalgo, alias Sixeart, ... who was one of the artists featured in the Tate Modern exhibition, started scrawling his name on the walls of his native Badalona, a suburb of Barcelona, in the late '80s, when graffiti was still a novelty in Spain. Despite lacking a formal artistic training, he decided to add a paintbrush and canvas to his usual tools, to great effect: His surrealist, childlike style struck a chord with audiences and art collectors the world over. Today, he is being mentioned -- and exhibited -- together with the likes of Joan Miró and Antoni Tàpies."
