Born in Irun in 1964, Iñigo Muguruza was part of a family of musicians. Together with his brother Fermin founded in 1984 the Kortatu group, a band of great importance in the history of rock in the Basque Country: thanks to the electrical combination of punk, ska and reggae, they signed many of the most important songs of the 1980s.

He was a bassist of this group and published four albums, initially sung primarily in Spanish, until the album Kolpez kolpe (1988) was published entirely in Basque.

This work already announced the following leap: Negu gorriak, rock, rap and many other styles fuse the band that gave much to talk about in the 1990s.

In this second group Iñigo Muguruza went on to play the guitar and he still has time to be part of another significant group: Delirium Tremens. He worked as a second guitar on three aeroplanes, signing for many the best album of the group.

When Irun's group released the Song of Corruption accusing him of being involved in drug trafficking, Civil Guard Lieutenant Colonel Enrique Rodríguez Galindo embarked on another project: José Ripiau.

Muguruza jumped to other records, with a warm and fun music. In addition, for the first time it was the main voice of the group, as well as playing the bass. His brother Jabier Muguruza also joined this project and edited four albums between 1996 and 2000, including the Paradisu film, where each song revolved around the theme of a film, thus showing his fans of Muguruza's film.

Starting in the 2000s, it was also part of three other groups: Sagarroi, who started making hardcore style to then move to the mestizo sounds of the ska; Lurra, the group that worked the acoustic melodies; and Hiru Leike, the group created together with Ane Odriozola and Paula Andrade.

When Lurra was part of the group, he announced that he was suffering from multiple sclerosis and that due to this disease he was going to interrupt. However, after the dissolution of this group in 2017 he continued to make music.

At the age of 54, the musician died, an essential figure in the soundtrack of a whole generation of musicians.
