1 hit, 100-150ug=Tripped, it was awesome, but no noticeable lasting change. I'm happy with that, doesn't matter if it does or not next time.
I haven't really listened to the Dead yet, but I heard "Anthem of the Sun" and "Aoxomoxoa" are really psychedelic. I also heard that the original mix of "Aoxomoxoa" is the one to get, and you can find vinyl rips online. Psychedelic rock is definitely amazing for acid!
LOL! Every now and then I'll listen to an old tape and hear Jerry do something on guitar that blows my mind. Like a chord progression that sounds like a roller coaster flying down a spiral or something like that. Fuckin blows my mind. I can never find those good parts to show my friends and they think the Dead's music is just good dance music not trippy head music. Following the dead and everything the cold hard road life entails brings their music into context. Someday I should write short stories about my Dead following experiences.
