I've used similar cds too, like Ultra Meditation. It's just binaural beats (like Centerpointe and Gateway) that drives your mind into a deep theta and alpha state, but it puts your mind in altered state very quickly. And you can do a lot of exploring in those states.

I've had some my best experiences when I started choosing specific goals I wanted to achieve and using these types of cd's during meditation to focus on them.

For example, if I wanted to have a lucid dream, I would specifically choose that goal and then spend time listening to the cd in a theta state focusing on that goal. I found that my mind was quicker to respond to specific goals and requests.

I also practiced staying alert for longer and longer periods of time in a delta state, which helped alot for lucid dreaming, and exploring different states of consciousness. Gateway's Voyages may even be more effective because it also comes with a plan for specifically expanding your consciouness...

For another which I haven't had experience with, is Tibetan bells which doesn't use binaural beats, but is said to drive the mind into trance-like states using sounds from ancient instruments used by tibetan monks.

It is also claimed that the users commonly reported being able to see 'auras' and 'energy fields' after frequent use...
