This is an enhanced audio CD which contains regular audio tracks and multimedia computer files. The last track "Le Soleil Est Pres De Moi" contains footage shot by video director Mike Mills during Air's sold-out tour of the United States and Europe in the Fall of 1998.

The five tracks compiled on the PREMIERS SYMPTOMES EP constitute nearly all Air music pre-MOON SAFARI, formerly available only as import 12" singles. So not only do these songs serve as raw recipes for Nicolas Godin and JB Duckel's magical blend of sweetly mellow soundscapes, reservedly downbeat tempos and creamy, luxurious melodies, they are arguably the duo's definitive moments. The brassy overtures of "Casanova 70," the funky Moog and sitar duet on "J'ai Dormi Sous L'eau" and the vocoder phrases announcing "Le Soleil Est Pres De Moi" make sure that dark clouds never block the sunshine. As is always the case with Air, the mood is conveyed through heavenly textures, not earthly beats, the two Frenchmen losing their heads in the blue sky to escape the dance floor's grounding monotony. PREMIERS SYMPTOMES is as good as calm, bright and happy music gets in the late nineties.
