About Un Singe en Été
Un Singe en Été: Musical Discovery in the Heart of Mayenne
Since 2015, the Un Singe en Été festival has established itself as a must-attend event for contemporary music in the Mayenne region. Organized by the association Tribu Familia, it takes over the Parc du Château de Mayenne each year, a remarkable heritage site by the river, to offer two days of concerts, performances, and artistic encounters on the last weekend of June.
A Bold and Eclectic Program
The uniqueness of Un Singe en Été lies in its program that rejects genre boundaries. Independent rock, electro, hip-hop, experimental pop, world music, folk, and unclassifiable stage performances share the stage across the festival's various areas. The commitment is clear: to highlight emerging artists and unique artistic proposals, where the lines between disciplines blur in favor of raw emotion and discovery.
A Heritage and Friendly Setting
The Parc du Château de Mayenne provides an exceptional backdrop for the festival. Several areas punctuate the experience: the open-air concert stages, the Château stage inaugurated in partnership with the Musée du Château de Mayenne for more intimate formats — DJ sets, short performances, and hybrid projects — as well as the Chill Zone, a space for relaxation and discovery. The warm atmosphere and the festival's human scale foster proximity between artists and festival-goers.
Strong Commitments
Un Singe en Été upholds strong environmental and social commitments. The festival prioritizes short supply chains and local products for its catering, with stands like L'Imotep (organic and local vegetarian world cuisine) and La Kantauch (artisanal nomadic cuisine based on Mayenne products). The payment system is entirely cashless, free drinking water stations are available, and reusable cups are encouraged. The festival also engages in year-round cultural activities in the Mayenne Communauté territory, including creative workshops with the Conservatory and training in collective catering.
A Growing Festival
Since its first edition in 2015, Un Singe en Été has continuously grown and reinvented itself. Many renowned artists have performed their early shows here before conquering a wider audience: Étienne de Crécy, French 79, Yuksek, Hervé, Arnaud Rebotini, and Favé and Kévin Morby have marked past editions. In 2025, the 11th edition brought together an ever-larger audience with artists like Warhaus, This Is The Kit, Zombie Zombie, and Boston Bun. The 2026 edition promises an equally exciting lineup with Shame, Maureen, Tramhaus, Myra, and Alma Rechtman.
Un Singe en Été — edition 2026
The 12th edition of Un Singe en Été will take place on June 25, 26 and 27, 2026 in the Parc du Château de Mayenne. The festival opens on Thursday, June 25 with a free before party in the Cour du Musée du Château, followed by two paid evenings (Friday and Saturday) of contemporary music on three stages — Magnolia, Remparts, and Château. On the program: Shame, Tramhaus, Maureen, Kalika, Myra, Coline Rio, Alma Rechtman, Magi Merlin, Changeline, Antilogic and many more.
