This CD contains the first-ever recording of Gurdjieff's piano music to be accompanied by sung prayers from All and Everything.
Having experienced the performances where these were recorded, I can attest that the vocal pieces have a powerful energetic resonance, and even more striking ideas and sentiments.

If the listener meets this music at least halfway, it is capable of changing one's vibrational state.
This is what Thomas deHartmann (the composer who helped Gurdjieff transcribe and harmonize the music) had to say: "If we compare it to the music of all the religions, we can see that music plays a great role, a great part, in so to say, religious service. But after the work of Georgi Ivanovich, we can understand it more, we can understand it better, that music helps to concentrate oneself, to bring oneself to an inner state when we can assume the greatest possible emanations. That is why music is just the thing which helps you to see higher."
