In 1987, Universidad de Chile disputed the last places in the honor series, while the official bar at that time, Imperio Azul, commanded by Eduardo Martínez, young fans, mostly of the thrash metal and punk style, who participated in it began to gather and they stood below it, glued to the fence, singing and encouraging the team with a couple of canvases with the text "Devotos del Bulla" and "Con la U Siempre", which broke the traditional scheme by incorporating phrases referring to the identification of the fans towards the team. Some of his modernizing ideas clashed in part with the generational barrier made up of the other members of the fans. Among these ideas was eliminating the snare drum and letting the bass drum sound alone and to one beat, in the Argentine way, streamlining the songs and giving a more active and aggressive attitude to the attitude that the fans should have.
