Throughout this outrageous musical suite, and in an apparently offhand manner, Les Grandes Gueules show us their almost childlike poetry, unfettered by the limits of any accepted school.  Their original choice of repertoire shows links to the Oulipo approach, they play on words and sounds with airy virtuosity, freely exploring an expanding universe where rhythmical ideas, a subtle blend of forms and movements and thematic development mingle the wondrous with the familiar.  The result is a truly new vocal phenomenon.  The rhythms of the planet become their playground, jubilant sonar landscapes springing powerfully yet delicately into life.  Using only their voices, creating deliciously refined musical atmospheres, whistling, clicking their tongues, rubbing their hands together, laughing and using their mouths to produce sounds of all kinds, Les Grandes Gueules project their sheer joy in singing to their listeners, transporting them on a voyage of discovery of new and hitherto unknown vocal dimensions.  Their luxurious sound and happy blend of voices surely make them one of the rare a cappella groups to have its own style, with a popular idiom at once rigorous, free and healthy, radiating with passion for music.
