In Ainhoa, Atsulai Abesbatza and the Chorale du Lavedan place Basque song inside the resonant setting of Notre-Dame de l’Assomption. The program joins traditional and contemporary repertoire, making the concert a meeting point between language, harmony and local sacred space. Its cultural value is in the continuity of voices carried by an ensemble rather than a single performance effect. The sacred building matters editorially because the repertoire is heard inside an architectural and acoustic setting already tied to village memory.
