Gurdjieff Two

One of the key things about Gurdjieff (I posted about him a couple of days ago, here) is that at the core of his writings is esoteric knowledge. Is it any wonder then, that I should be sitting at breakfast the next morning reading, and came across an interesting fact? I was browsing through an article about Van Morrison in the latest issue of Uncut media magazine. It transpires that Van Morrison experimented with Christian Mysticism, Buddhism, Scientology, Hinduism and Gurdjieff. That would help to explain some of the mystical qualities of his music when he slips into the zone. So, I am aware of the influence of Gurdjieff on Keith Jarrett, Van Morrison, Robert Fripp and, I think, David Sylvian. Is it significant that most of these are prolifically creative?

Do you know of any other artists who are influenced by the work of Gurdjieff, Ouspensky and Bennett?
