Since 1924 there have been many excellent recordings and concert performances based on the Gurdjieff - deHartmann music; though in my experience none other than The Gurdjieff Folk Instruments Ensemble have had the authenticity of the sources of the music Gurdjieff brought to us; with these arrangements and these instruments we are brought nearer to the sources of the Gurdjieff music, be it folk melodies, sufi songs, or Orthodox hymns.
To witness. like I had the opportunity on Friday the 20th in Stans, Switzerland, an audience of over 500 people in a Catholic Church, silently iistening for a couple of hours also shows that the right place to hear this music is a Church.
Let us hope that the Movements and Dances can follow!
