Created in 1993, the band recorded their first album, Le Bien-être et la Paix ("Well-being And Peace"), four years later. After this album, Mass Hysteria's breakthrough album came in 1999 with the release of Contraddiction which sold to over 50 000 copy. The album itself is still widely regarded as the band's iconic Black Album. It was produced and mixed by Colin Richardson.

In 2001 the band returned after intensive touring with a different approach with the release of De Cercle en Cercle. This album received mixed feelings with the arrival of new guitarist Olivier Coursier. The album's new pop/rap experiment approach left the band isolated from the metal scene. Michel Houellebecq, met in Québec, was supposed to write one of the songs but the agreement was never concretized. In 2005 the band released Mass Hysteria confirming the band new soften pop/metal approach.

Finally, in 2007 with the departure of Olivier and arrival of Nicolas Savoury the band returned with Une somme de détails ("An addition of details"). The album pushed Mass Hysteria back to its root of origin that made it a success. The album heavier than ever began to close-in on Contraddiction dangerously. Two years later in late 2009 the band released Failles (cracks). The album's cover undeniably confirmed the band renewed past with Contraddiction (also in red and black). The album received critical acclaim.

In the mass media, Mass Hysteria was known for some controversies and incidents surrounding them. But some critics have also noticed the quality of their music and their growing success.
