having recently been to the Arhtur Findlay College on an experimental trance week, i must say that the teacher had played this during our developmental meditations.
all i can say is WOW.
the actual noise that is made may not make much sense when first start listening to it, but over all, the more you listen and the more yu manage to pick up the very subtle undertones to it, the nicer and deeper you feel as you progress in meditation.
i found this cd to be of a great benefit to me in my development, as well as that, i also found it extremely relaxing on a whole.
i play it frequently at home and on YouTube as well, so if ur interetsed, yet want to smaply it, it's on YouTube, and im sure you'd be hooked by it.
It is long, but time flies when your having fun, and as already said, the undertones allow you to simply fly wherever you want to go :-)
highly recommended for anyone who does and wants to use music for meditation
