Its long career and recent tours in the United States have made it one of the most important and popular punk bands in Medellín and Colombia.
("Sucios y Desordenados Anarkistas") ("Dirty and wild Anarchists"), by a group of friends that used to meet in the El Poblado park in Medellín.
In 1990, Jose Juan, who used to hang out in Poblado park and walk down the streets all around the city, rented a house with his buddy Chozas.
The Punk House became the place where the Medellins underground scene survived and grew strong during the violent times of the narcoterrorist war.
(Bastardos Sin Nombre), Dexconcierto, Reencarnación, Crimen Impune, C.T.C., Nada, Antioquia Podrida, Ataque de Sonido and others.
On this album, José Juan, a founder of the band who had left in the previous year, returned to play the guitar, but only as a guest musician.
In 1999, the band played in "Rockatón", a concert to raise funds for the people affected by the earthquake in the "Coffee Region" of Colombia (Caldas, Quindío, and Risaralda).
In March and April 2004, the band toured the United States, there they had fifteen performances in Boston, Baltimore, New York City (where they performed in the famous CBGB, and during which the band recorded a live album), New Jersey, Miami (where they filmed the video of the song Explotados ("Exploited")), Monterrey, Berkeley and San Francisco.
In June of the same year the band began a new tour through the United States, releasing there their new album and performing in several cities, including again CBGB in New York, and they filmed the video of the song Vivir para esto ("Live for This") in Miami.
Mónica and Viola decided not to replace him and to invite other musicians to play the bass in live performances and future album recordings.
