I bought this cd because more instruments were played in addition to the traditional drums of say, Shamanic Journey Drumming by Rysdyk. In the end though, I feel that Rysdyk's recording is the better choice.There are two things that I really don't like about this cd:The first is the metallic quality of the drum sound, which reminds one of a synthesizer. Rysdyk's drums have a deep, cavernous quality that is simply wonderful, specially if you listen to them with earphones on. Strange to say, the drums on this cd are strident. There is no space in the sound in which your spirit can move.The second problem is the constant background incantation.What I take to be some kind of prayer to the spirits sounds so eerie and ghostly that I couldn't listen to this cd for more than a few minutes. I was afraid of becoming possessed or attracting some unwelcome visitors from the lower planes.So think twice before buying this cd.
