Drums & Rattles? Haha, Kenny, that was a bit of a joke based on my introduce yourself post. As I'm actually headed to Mexico to participate in an Iboga retreat. I don't take these things lightly and back when I did do them at home with music, it was mainly mushrooms and Shpongle to answer your question. If you read my introduce yourself post, you'll see that I am building a company with a few close friends called Subtle Energy Sciences ( http://Subtle.Energy )
Check out some of the products we have listed there, no psychedelics required. They aren't really based on sound but on subtle energetic frequencies and torsion field technology made from simple shapes.
