Background
Gojira made history as the first metal band to perform at an Olympic opening ceremony. The performance took place on July 26, 2024, from the windows of the historic Conciergerie in Paris. The band collaborated with French-Swiss mezzo-soprano and former heavy metal singer Marina Viotti and composer Victor Le Masne to reinterpret the French Revolution-era anthem Ah! Ça ira.
The title combines the Latin phrase Mea culpa ("my fault") with the revolutionary slogan Ah! Ça ira ("It will be fine").
Composition
The song blends Gojira’s signature heavy metal sound with operatic vocals and orchestral arrangements. It opens with chanted refrains of Ah! Ça ira and Mea culpa, layered over heavy guitar riffs and cinematic percussion. Viotti’s operatic delivery contrasts with Joe Duplantier’s growled vocals.
The track was arranged by Victor Le Masne, known for his work in classical and pop crossover productions.
