Sometimes, crazy people are not such and by their deeds they create actions that change the world, or at least the way to perceive it. Maybe, the crazy people in this case were only dreamers who dared more and to this day we celebrate their dreams.

"Los Locos de la Azotea" was the name given to a group of friends who, a day like today, but 1920, they would forever change the way they inform us, entertain and listen to us. A 27 August 1920 the radio was going to arrive in our country.

That group was made up of Enrique Susini, Cesar Guerrico, Luis Romero Carranza and Miguel Mujica, who exactly from the 21 and from the roof of the Teatro Coliseo, they broadcast live the opera "Parsifal". Without knowing it, they were kicking off what would become the Argentine radio.

Few people that day were able to hear those stanzas of Richard Wagner's work and they would never even realize that they would be silent witnesses to an event relevant to history, not only in Argentina., fate worldwide.

From that moment, radio has evolved both in content and in its formats and technology.. Perhaps today the podcast is his last member of his succulent lineage so far. The truth is that from the early news, the radio soap operas, the endearing voices and the fact of being accompanied by a voice that had no face, made radio one more member of the family.

Going back in time, more precisely in 1910 and in Bernal, town located south of the Buenos Aires suburbs, Guillermo Marconi had been the one who gave the first advances with his inventions that would conclude in a communication with Canada and Ireland, thanks to the kite on which an antenna went up.

This was a trigger for the media back then, that reflected the progress on its pages. The "Locos de la Azotea" were also inspired by these publications when developing their idea.

After World War I, Susini, in full development of his medical career, would travel to Europe in order to study the effects of asphyxiating gases. That trip was key, since in France it was made of equipment that would later be used in the transmission that took place in the Colosseum theater.

Those equipments looked like junk that was abandoned by the army, transmitters 5 Power kw, were received with open arms by Susini. In this way, the group of friends added a deaf speaker to a microphone and placed it in the upper area of ​​the Colosseum hall.

As for the transmitter, proved vital from his rooftop stand, while the antenna was a simple wire located between the theater and the dome of the home of César Guerrico, located at the crossroads of Cerrito and Charcas (currently Marcelo T. Alvear), just a few 25 meters away.

Of the four friends, Susini would perhaps be the most remembered, since his voice would be captured forever in the first transmission, expressing verbatim: "Ladies and Gentlemen, The Argentine Radio Society presents today the Ricardo Wagner Sacred Festival, ‘Parsifal’, with the performance of the tenor Maestri, the baritone Aldo Rossi Morelli and the Argentine soprano Sara César, all with the orchestra of the Teatro Costanzi in Rome, directed by maestro Félix von Weingarten ".

Made that dream come true, the next day "Aída" was broadcast, again "Parsifal" and "Iris". With this milestone, the first broadcasting license would also arrive, the LOR, Radio Argentina.
