I know its been mentioned before, but since i have done it successfully 16 times i am going to post some experiences and tips.
Astral Projection = the best. They are easily the gateway to insanity.
First i start off by getting a small history of their musical background, what they like, if they played anything. Then i mention Goa briefly.. a small history, which I found most people find interesting enough to look it up on their own. From there if the victim, I mean friend inquires more you can hook them up with a cd, maybe some tracks they like (disturbed, whatever) with some astral thrown in. Older astral works best.. so you have room to build. Then without high pressure sales i find out if they liked the astral tracks thrown in, if they did what elements they did like, what they didnt like, then compile another cd hitting closer to home. It doesnt hurt that my friend works for a government institution that makes parts for military aircrafts, so he gets lots of cool free samples like fiber optic pens and cool mini lights, that also adds to the fun of getting a new disc. By that time if things went smoothly they can actually indentify what they like, you can add some names like posford, x-dream, cosmosis, old infected. Then they are off on their own. I promised myself i wouldnt cry.. heh
My girlfriend is completely addicted at this point, she loves Astral, and Shpongle. Her best friend tiffany, she likes the same.
Best friend he likes MWNN and Eat Static, also Astral. Another friend likes boris blenn alot, some Pleaidians, Astral as well. Another friend started with Astral, but now he found his way to Posford. Another friend heard Mahadeva as his first track and that was that. My latest victim, I mean friend is 100% Astral now. I think he packed his bags, left his old music, ran away to Goa-land and is never coming back.
