Atturi Ondo Kantuz gathers hundreds of voices around Basque song in Bardos. Local groups and schoolchildren make the event intergenerational, showing how repertoire survives when it is sung publicly rather than only archived. The gathering gives the Adour area a living choral moment, rooted in language, collective memory and the discipline of singing together. The presence of schoolchildren is central, because it shows transmission while it is happening, with younger voices entering a public Basque repertoire.
