I picked up "Gomang chants" recently. it is Tibetan sacred music. I don't listen to it for the purpose of entering trance, but listening to it does make me mindful of spirituality. i might be able to enter trance with it, but I am more likely to use the monroe hemisync for that. I greatly enjoy the chants.

I see where your going... a technique I use is playing with the music in my mind. (I'm a drummer, and its instrumental music.) It works for me, but it would be cool if others tried this too.
i do listen to 1 particular CD as i do my visualizations. it helps me enter trance states more often than not. Kitaro - Ancient is the artist - album title
does anyone else listen to music for similar purposes? if so, what kinds?
