A basaltic rock is placed on the ground, mosses develop there. It seems that this colonized volcanic stone breathes, one hears like a snoring, a grunt. The body of the mineral is dug to shelter a sound device diffusing a double sound, that coming from the depths of the earth, of an earthquake, the other the roaring breathing of a panther. These rumblings harmonize to give a kind of telluric snoring. Dissociated, the vegetable, mineral and animal kingdoms merge here to generate a hybrid being.
