Poly'Sons Festival

23rd Edition - All the voices of francophone song

For its 23rd edition, the Poly'Sons festival made all the voices of francophone song resonate in Montbrison from January 15 to February 8, 2026. The Espace Guy Poirieux once again hosted the majority of the concerts, with events also scheduled in partner venues.

The festival opened on Thursday, January 15, with the Saint-Étienne duo Terrenoire, who confirmed their status as ambassadors of the new francophone scene. On January 16 and 17, the legendary French rap group Sniper set the Guy Poirieux hall ablaze.

Among the highlights of this edition, Marie Jay and Klô Pelgag shared the stage on January 21 for an evening of discoveries. Thomas Fersen unfolded his poetic and quirky universe, while Rose offered a concert imbued with electro-pop sensitivity. Melba introduced her mixed musical universe to the Montbrison audience.

La Grande Sophie performed on January 30, bringing her rock tinged with melancholy. The closing evening on January 31 brought together Les Croquants and Debout sur le Zinc, two bands known for their communicative energy on stage, guaranteeing a festive and memorable finale.
