After the
Spanish 1977 Amnesty Law, he returned to Spain and continued his musical career in the
Basque Country, engaging in various initiatives in defense of Basque culture and language such as the
Korrika, a biennial 11-day nonstop running event that promotes awareness of the
Basque language and adult education in Basque. Imanol drifted away from the ETA environment: although politically he continued to favor
self-determination for the Basque country, he came to
oppose violence in favor of singing to stir the conscience of others to the Basque cause. On June 10, 1985, Imanol was arrested along with his technical team after involvement in the escape of ETA prisoners
Joseba Sarrionandia and Iñaki Pikabea from prison in
Martutene. After Imanol performed a concert in the prison, the prisoners escaped by hiding inside two loudspeakers that were loaded into the group's van. However, Imanol was released after investigation. In 1986, Imanol participated in a concert in honor of ex-ETA leader
María Dolores Katarain (known as
Yoyes), who had been murdered by her former colleagues in the town of
Ordizia after she tried to leave ETA. Imanol's participation resulted in many of his fans and colleagues boycotting and excluding him from recitals organized by
Herri Batasuna. The sales of Imanol's records decreased as political aspersions against him increased. In the following years, he received death threats in the form of graffiti and vandalism of his car. On September 21, 1989, Imanol performed another concert for
Yoyes. As a result, threats against him intensified. In response, a group of friends including some cadres from
Euskadiko Ezkerra of Ordizia proposed organizing a further concert in support of Imanol. On November 2, 1989, Imanol announced a performance entitled "All Against Fear" would be held 3 days later with the participation of several other Basque artists. The following day, even more joined to perform, including improvisational singers (
bertsolaris). Telegrams were read from the union
CCOO and about 180 former ETA prisoners signed a statement in support of Imanol and rejected the "obligatory thinking" of the terrorist group. Although some of the signatories later withdrew their support, Imanol was given 150 signature sheets of support on the day of the concert. A month later, Imanol was to perform in
Ataun along with 8 other artists at a tribute to
Jose Migel Barandiaran for his hundredth birthday. Only 2 of those 8 artists were willing to share a stage with Imanol, the others opposing Imanol's presence or trying to avoid involvement in extra-musical matters. ==Second exile==
