They started rehearsing in the house of a friend, but were soon thrown out because of the noise and disorder of the public that attended; they then began to rent one of the first rehearsing places that existed in Medellín, where the quality of the sound was bad. Still, it was one of the few options that the band had in order to continue.
In 1986 they changed the name of the band to I.R.A. ("Ideas de Revolución Adolescente") ("Ideas of Adolescent Revolution"). By this time, they had already found other places to rehearse in friends' houses and abandoned places, but those were rehearsals with little or no public, hoping to avoid problems.
In 1989, the band had its first performance; it was in the La Visitación neighborhood of Medellín. The same year, the band records in Chava Bluss Studios its first work: Barkizidio, a 7" EP with nine songs.
In 1990, the band had several performances. In these, they played alongside some of the most important underground bands of that time: B.S.N. ("Bastardos Sin Nombre"), Dexconcierto, Reencarnación, Crimen Impune, C.T.C., Nada, Antioquia Podrida, Ataque de Sonido and others. The same year Yoryi (drums) left the band and he was replaced by Marcelo. Also, the band performed outside Antioquia for the first time in a performance in Pereira, Risaralda, organized by punks of a neighborhood of that city.
In 1991, the band recorded in Raimond Records Studios its second EP, Atentado Terrorista, which contained eight songs, with bass sounds recorded by Viola, replacing Jose R, and the second vocals by Mónica, who had been with the band since 1990.
In 1993, the line-up changed again; the new drummer is Kamel, replacing Josesito, who replaced Marcelo in 1992; Federico enters the band as the new bassist, Mónica and Viola continued to do the vocals and José Juan the guitar. With this line-up the band recorded the LP Impotable Diversión. They also did a tour in Ecuador, where they performed in Quito, Ambato, and Cuenca.
In 1996, the band recorded in Pussy Music studios its first album in CD, Crónicas de una década podrida, containing 26 of their songs composed between 1986 and 1996; it was released in the Palacio de los Eventos of Medellín in a performance alongside the band Neus.
In 1997, José Juan left the band and was replaced by Federico, who was replaced on the bass by Cabe; Kamel also leaves and was replaced by Aníbal; with this line-up, the band went to Venezuela, there they played at the Poliedro in Caracas; later on, during that same year, Federico also left the band and was replaced by Viola.
In 1998, the band recorded three songs for the compilation Ideas encontradas, produced by Sin Piedad Records. The same year, more players left the band: Aníbal, who was replaced by Fredy, and Cabe, who was replaced by Gabriel. With this line-up, the band recorded its second album in TKG Records and Organic Sound: Entre amigos. In this album, José Juan, one of the founders of the band that had left in the previous year, returned to record the guitar, but only as a guest musician.
In 2000, Fredy left the band and was replaced by Mónica. This same year, the band performed alongside bands like: Fértil Miseria, La Zorra, Ácido Folklórico, Coffee Makers, Dumka Diskantus, 2 Minutos, 911, Tr3s de Corazón, Mojiganga, Grito, 5 de Menos, Tres Hombres and La Siembra.
In 2003, they recorded, in El Pez studios, their third album: Epidemia de Infexion Respiratoria Aguda. This album contained 14 new songs, 14 new versions of old songs and nine songs recorded live; alongside the album the band released its first video, of the song Lo que ustedes se merecen ("What you deserve"). The band also did a short tour in Colombia, performing in Medellín, Bogotá y Cali simultaneously with the release of the album in these cities. Later the same year the band released its second video, of the song Neurona ("Nerve cell").
In March and April of 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. When the band returned to Colombia, they began a new tour through Colombia, performing in Bogotá, Cali, Manizales, Ibagué, Bucaramanga, Armenia, Rionegro and Medellín where they performed alongside the American band Molotov Cocktail. In December they played in the Altavoz Festival 2004, in a performance in the bullring La Macarena of Medellín. The band also recorded its fourth album Décadas de libertad which would be released the next year.
In March of 2005, the band played at the Ancón Festival 2005. Later, the band performed in Ecuador and Venezuela. After returning to Colombia they released their new album, Décadas de libertad and a documentary film about the band: Documentira. 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 the CBGB in New York, and they filmed the video of the song Vivir para esto ("Live for This") in Miami. In August, after returning from the United States, Gabriel leaves the band. Mónica and Viola decided not to replace him and to invite other musicians to play the bass in live performances and future album recordings.
