From NPR/music: Deceptive Cadence on G.I. Gurdjieff

The Master

by Tom Huizenga

Many westerners (me included) had never heard of George Ivanovich Gurdjieff until the early 1980s when pianist Keith Jarrett released Sacred Hymns [Triangle audio cassette boxed set], a rather austere but beautiful album devoted to Gurdjieff’s music.

A new album, directed by Levon Eskenian, sets music by the spiritual leader and composer G. I. Gurdjieff for traditional Eastern instruments.

After I first heard those Eastern-tinged melodies, a little research revealed that Gurdjieff was much more than a composer. He was in fact a major spiritual leader, philosopher, author and traveler who was born sometime around 1866 in the Russian city Alexandropol, which is now Gyumri, Armenia.”

See the full article here.

But, if you really want to study about G.I. Gurdjieff, there are many books devoted to his life and work, and you are going to need to procure some and really read them. Charlatan or giant, this is a figure larger than life.

The current acknowledged standard of excellence for the music of Gurdjieff is The Complete Piano Music of Georges I. Gurdjieff and Thomas de Hartmann (6 CD Boxed Set) [Box set]
recorded by Cecil Lytle on Celestial Harmonies (1997)
