Un Singe en Été

11th Edition — Boldness Takes Center Stage

For its 11th edition, Un Singe en Été offered a program resolutely focused on discovery and experimentation. The festival took over the Parc du Château de Mayenne on June 27 and 28, 2025, with a lineup of artists with diverse and complementary universes.

Lineup

Friday evening vibrated with urban rhythms featuring Jolagreen23, YVNNIS, Théa, and Syqlone, while Saturday offered an eclectic musical journey with Warhaus (Belgian folk-rock), This Is The Kit (Kate Stables' folk), Zombie Zombie (hypnotic krautrock), Boston Bun (French Touch), Miki and Whisper (new French pop), as well as GoGo Green and Jean-Paul Groove.

New Feature: The Château Stage

The Château stage, inaugurated in 2024 in partnership with the Musée du Château de Mayenne, became a true space for artistic experimentation in 2025, hosting DJ sets, short performances, and hybrid projects. An unprecedented free pre-evening event kicked off the festivities on Thursday, June 26, from 6 PM to midnight, in the museum courtyard.
