Now in its 9th edition, Mama Stock is a free, family-friendly festival held each August at Parc Montcalm in Montpellier. Born in 2017 from a tradition of neighbourhood parties and popular celebrations, it regularly draws between 12,000 and 15,000 visitors over its run. The festival's ethos centres on living together, democratising culture, and supporting regional artists, all while remaining entirely free of charge.

Thursday 27 August opens with Expo Anagraphis and Expo Découverte in the chill-out space (12:00–18:00), followed by Sophie les Bas Bleus on the main stage at 19:00 — a group mixing accordion, rap and rock — and closing with Pizzetto DJ Set at 21:00 on the main stage.
