It was established by César Fuentes Rodríguez, along with other journalists from the former Riff Raff magazine.

Unlike the Metal magazine, it had an informal style and wrote harsh critics to recordings or plays they did not consider of good quality.

The magazine released some special editions as well, titled "Madhouse extra".

Some bands that got a special edition were Hermética, AC/DC, Kiss, Pantera, Megadeth, Marilyn Manson, etc.

César Fuentes Rodríguez left Argentina and moved to Spain for a few years.
