It is very hard for me to explain. I have a lot of trouble explaining what it is about music such as La Voyelle Liquide that I enjoy so much. It has something to do with mood and atmosphere, something to do with variety within a limited palette of sounds, perhaps something to do with the novelty of the sounds and music created - it is radically different from any other music in my collection and, when in the right mood, I really love listening to this.
It is definitely not for everybody and is probably not to most people's tastes, which is fine. I'd advise holding onto the disc for a few months or so and coming back to it. I had a lot of trouble with my first eai disc, The Hands of Caravaggio, but, eventually, everything started to click. Conversely, this music may just not be for you, in which case wait until it if "officially" oop and get the best deal you can for it on ebay.
Thanks John.
