Influenced by the Spanish literature, Iniesta's lyrics are often described as rude street poetry, with frequent allusions to drugs, sex and self-destruction.

Previously, in 1983, he had formed the band ‘Dosis Letal’ with Zósimo "Zosi" Pascual, with whom he composed the song "La Carrera",[7] that would later come to be the penultimate track of Extremoduro's 1996 disc Agíla.

This initial set-up lasted just a few months, after which Robe decided to reconfigure the group and found Salo and Louis "von Fanta" to replace Kaito and William respectively.

With this new dynamic in place, and with the difficulty they faced recording an album, they decided to sell vouchers to their acquaintances (at a thousand pesetas each) that would entitle each of them to a copy of the demo tape after it had been produced.

The distribution of this transgressive musical offering of rock began to attract attention inside and outside their home region of Plasencia; it was so well received that the Spanish television program Plastic[8] invited them for a live performance.

In 1991, a deal was struck with Wasp to record the second album, but due to the poor expectations that the label offered, they decided to break this contract and sign with Pasión-Área Creativa,[9] like Avispa Music, an independent company, but this time with better conditions.

With the collaboration of vocalist and guitarist Madrid Rosendo Mercado (ex-Leño) on the songs " La canción de los oficios " (voice) and " Perro Callejero " (guitar), they themselves define it as the beginning of the true sound of Extremoduro that the band calls "transgressive Rock."

The group began to sell a lot and Pasión-Área Creativa proved too small for their ambitions, which together with other disputes (royalties not being paid for this LP), lead to them signing with DRO in 1991,[9] giving them better distribution and promotion, and the means to the success that later years brought.

The album has a more erotic—and less social—theme than the previous discs, and most of the lyrics are adaptations of the poems by Kiko "Luna Creciente", Tomás Rodríguez (the band's manager) and Manolo Chinato.

For starters, they cross paths with Iñaki "Uoho" Antón (then guitarist of Platero y Tú) in Bilbao and together with other musicians start a new project: La Pedrá.

After being part of the band since recording the demo, and three albums, drummer Luis "von Fanta", bassist Carlos "el Sucio" and guitarist Salo left the group.

It was with this collection of musicians that recorded the fourth album: ¿Dónde están mis amigos?, Which continues the style begun with Deltoya and confirms their reputation as one of the most important groups of Spanish rock.
