Elgarrekin brings thirty-five singers and four musicians into Saint-Jean-Pied-de-Port for a program rooted in Basque polyphonic song. The choir’s strength is its openness: it defends inherited choral repertoire while moving toward other musical cultures. That makes the performance a living practice of language, harmony and exchange rather than a fixed heritage display. The ensemble’s size also matters, because many voices and musicians create a public choral body capable of carrying language, harmony and local memory.
