“Casus Belli”, is the first orchestral sound piece by Ex Abruptoproduced for the contemporary creation festival MAU 2018 at Roca Umbert, Granollers.

Making war was the theme that Roca Umbert Fàbrica de les Arts proposed to all the participants of the exhibition, for the commemoration of the 80th anniversary of the bombings that during the Spanish Civil War suffered several cities, including Granollers.

With this premise, we designed and produced a sonorous journey of four moments prior to the outbreak of a war. The intervention was specially designed for this festival and specifically for La Tèrmica; an old building that houses the electric and steam generator that the Roca Umbert textile factory had when it was in operation between the 50s and 90s.
