I haven't used a relaxation CD before, so I can't really put this particular one in context. However, what I can say is that it had a very limited effect with me. While it was generally soothing, I found the relaxation I do without a CD or tape to be more effective. I also thought that it should be made clearer that the CD induces a semi-hypnotic state (especially in the second track). Overall, it hasn't helped with MY anxiety and panic attacks, but everyone is different and presumably different techniques and aids work for different people and conditions. The 2 star rating I give reflects the result of the CD on my condition and not the content quality (which is overall - pace, length, tone etc - quite high).
