Inspired by the cycle of work entitled "L'Empire des lumières" by René Magritte, the work develops four basic concepts; the idea of background vs figure, the idea of contrast, the textures of sound clouds and the idea of sound shadow, generated by linear deviations from one or several sounds.

The sound material is articulated around these main ideas throughout the work. This material is generated from a spectral treatment of harmony, based on the harmonic spectrum of the solo instruments (trumpet, flugelhorn and piccolo trumpet). These initial harmonic spectrums, configure the whole sound structure from the application of synthesis and filtering techniques. The resultant harmonic spectra, in turn, maintain a direct correspondence in the organization of discourse at the microformal and macro-formal level, thus generating the entire architecture of the work, starting from the genesis of the soloist instruments themselves. This spectral architecture, is seen at various times infiltrated rhythmic, harmonic and melodic material outside the spectrum, in order to give the work a greater sonorous richness. In this way, starting from very contrasting elements, a hybridization of materials is generated that result in a much richer, more varied and expressive discourse. Thus, in the second movement, by the analogy of deep singing, the spectral harmony is intermingled with elements derived from the arrow, which, in turn, generate new materials that will have their development in the following movements.

The four movements are:

I. Empire of light

II. Dark song

III. Cadenza

IV. Vortex to the sky
