This concert will be particularly special for the band, as they will be playing in the hometown of their bassist, Ania Guijarro. Dale Kaligula was formed in Berango in 2021, as a project among friends with the aim of creating music. The initial lineup included Jon Ander Diaz (percussion), Ander Mollinedo (guitar and vocals), Alex Briegas (guitar, synth, and vocals), and Jon Ander Ruiz (bass).

When Jon Ander Ruiz moved to the Netherlands for work, Ania Guijarro took his place in late 2024. Guijarro, who had known the band members for a long time, did not hesitate to join this new project.

With this new formation, the band released their first LP, Sasilanak, in November 2025, through Eten Espazio Sonoro in Bilbao. This album brings together diverse sounds, combining rock, pop, punk, and a touch of psychedelia, always in Euskera. The band, humorously, defines their style as 'psychopunk', as the ten songs make it difficult to classify them into a single genre.

In recent months, Dale Kaligula has been presenting the album across Bizkaia, performing concerts in towns such as Berango, Leioa, Sopela, Santzurtzi, and Bilbao. The performance in Eskoriatza will be particularly important, not only because it will be their furthest concert from home to date, but also because it is the birthplace of bassist Ania Guijarro.
