For already 30 years, Mass Hysteria has been delighting metal music fans with their high-energy performances. The band, now made up of Mouss Kelai, Yann Heurtaux, Raphaël Mercier, Frédéric Duquesne, and Jamie Ryan, released their debut album "Le Bien-être et la Paix" in 1997. However, it was their second album, "Contradiction," in 1999 that truly brought them widespread recognition. Since then, the Parisian group has put out eight records, each one sparking blistering live shows that leave audiences electrified.
In 2026, Mass Hysteria plans to go " Full Throttle". To celebrate their 30 years in the industry, the band has announced a series of eight special dates across the country. The concept? Intimate evenings featuring a mix of museum-style exhibits, meet & greet sessions, Q&A segments, and a retrospective concert.
Mass Hysteria is expected to make stops in cities like Rennes, Toulon, Strasbourg, and Montpellier. No date announced for Paris, but an exclusive show is scheduled in Val-d'Oise. Mark your calendars: catch Mass Hysteria at the Forum Vauréal on Thursday, November 12, 2026. To secure your spot, don't miss the ticket sales opening on Monday, December 15, 2025, at 11 a.m.
Through this innovative concept and intimate evenings, Mass Hysteria aims to connect more closely with their passionate fans. The "Straightforward" events will kick off with 45 minutes of question and answer sessions with the band members, followed by a 'retrospective concert' highlighting their extensive discography. An art exhibition curated by Corentin Charbonnier will also be on display, along with a meet and greet after the show. If this idea excites you, mark your calendar for November 12, 2026, at the Forum Vauréal. Tickets go on sale on December 15, 2025, at 11 a.m. — don’t miss out!
