Orléans Métropole's premier contemporary music festival
Created in 1990 by the City of Saint-Jean-de-la-Ruelle, Le Grand Unisson is the premier contemporary music festival of Orléans Métropole. Scheduled for two days outdoors and entirely free, "Le Grand U" brings together nearly 10,000 festival-goers each year at the IRESDA stadium. The festival is distinguished by its musical eclecticism, mixing nationally renowned artists on the main stage and emerging talents on the discovery stage. An association village, creative workshops, and fireworks complete this popular, intergenerational celebration.
Since 1990, Le Grand Unisson – affectionately nicknamed "Le Grand U" – has been the unmissable musical event in Saint-Jean-de-la-Ruelle and the Orléans Métropole. Born in the late 1980s in the Corbolottes district, where concerts were held on the roofs of buildings, the festival has grown over the decades to become a major event on the Loiret cultural scene.
Initially, the creation of a recording studio in Saint-Jean-de-la-Ruelle made the town a meeting place for local bands. As early as 1992, the festival evolved with the establishment of six "young talent" stages designed to give visibility to regional bands, in addition to a main stage hosting major national artists. In 2003, due to the growing influx of the public, the festival moved to the IRESDA stadium, rue de Bagneaux, where it has been held every year since.
The identity of Le Grand Unisson is based on the diversity of its programming. Rock, pop, French chanson, hip-hop, world music, soul, funk, folk, reggae, electro-pop: genres cross and respond to each other on the festival's two stages. The main stage hosts recognized headliners – including Tryo, Superbus, Amel Bent, Ben l'Oncle Soul, Gérald De Palmas, Kid Creole and the Coconuts, Les Négresses Vertes, KYO, Princess Erika, Emily Loizeau, and many others – while the discovery stage highlights emerging artists from the Centre-Val de Loire region.
Beyond the concerts, Le Grand Unisson offers an association village bringing together about thirty organizations that showcase the cultural, eco-responsible, and civic vitality of Saint-Jean-de-la-Ruelle. Drawing and graffiti workshops, composting initiation, games from the toy library, open-air reading areas, prevention and information stands: the festival is a place for sharing open to all audiences and all ages.
Catering is provided by local associations and artisans offering specialties from around the world, accompanied by local craft beers. Each edition concludes with a fireworks display fired from the stadium, a highlight that brings together young and old.
Le Grand Unisson is committed to sustainable development: reusable and compostable tableware, waste sorting, accessible pathways for people with reduced mobility, bicycle parking, and hearing protection awareness. The festival champions the values of free access, musical eclecticism, and openness to all audiences, making each edition a moment of popular celebration and togetherness.
The 34th edition of Le Grand Unisson will take place on June 12 and 13, 2026, at the IRESDA stadium in Saint-Jean-de-la-Ruelle. The festival will continue its tradition of two days of free open-air concerts, mixing established artists and emerging talents in a festive and friendly atmosphere.
Le Grand Unisson returns for its 34th edition on June 12 and 13, 2026. The premier contemporary music festival of Orléans Métropole will offer, as every year, two days of free open-air concerts at the IRESDA stadium, with an eclectic lineup on the main stage and the discovery stage.
The full lineup will be announced in Spring 2026 on the festival's social media and the website of the City of Saint-Jean-de-la-Ruelle. The association village, creative workshops, and closing fireworks display will be back.
