Le point de départ, c'est une commande de l'Opéra de Rouen Normandie : une œuvre pour un orchestre symphonique et le big band Tous Dehors, avec pour projet d'illustrer les différentes étapes de la vie, de la conception jusqu'à l'ultime souffle. Passé le stade de la création, il n'a pas été possible de rejouer la partition sur scène ni de faire un enregistrement avec l'effectif originel (une cinquantaine de musiciens). Laurent Dehors s'est donc remis à la tâche pour une version en effectif réduit : neuf musiciens, plus les deux solistes invités (Marc Ducret et Matthew Bourne) qui dialoguent avec l'orchestre. Le résultat est plus que convaincant de vitalité, de vivacité et de pertinence.
Feeling that Harmonium had released in L'Heptade (1976) the best album it could possibly make, its leader, Serge Fiori, disbanded the group in early 1978. At the same time, Richard Séguin also saw his folk group, les Séguins, fold after the release of its peak album, Récolte de Rêves. Fiori had a few songs that the Harmonium musicians had already begun to work on; Séguin also had a few left in his files. The two teamed up, writing three more pieces together and recording them with the last Harmonium lineup. The resulting album is indeed weaker than L'Heptade, but it is not the casual one-time collaboration one could expect. Conceived as a group effort (all the players were involved in the arrangements), it has a strong personality, the identities of both singer/songwriters melding gracefully…
To a backdrop of the apocalypse, torrential flooding and the threat of earthquake, a simple man embraces a curious nymph-like créature, pregnant and désirable, who stops clocks and awakens long-forgotten languages. Adapted from the work of José Rivera, "Cloud Tectonics" represents a singular approach to jazz-opera, masterfully written and performed by Laurent Cugny.
