In August 2007, when Arcade Fire graced the stage at Rock en Seine, they were riding a wave of soaring success thanks to their second studio album, *Neon Bible*, released just a few months earlier, in March of that year. This album marked a significant evolution for the band, blending their signature indie rock sound with more expansive, orchestral elements, which really resonated with fans and critics alike. It was fascinating to see them perform "Wake Up," a track that had already become an anthem and showcased their palpable energy, both in the studio and live. The festival itself, held at the picturesque Domaine national de Saint-Cloud, provided a stunning backdrop, amplifying the excitement of the band’s passionate performance. Interestingly, the band’s ability to connect emotionally with their audience during this era foreshadowed their continued evolution, solidifying their place in the indie rock landscape. Quite a moment, don’t you think?
