jeff, I'm surprised you haven't started a new thread with this!
I've had three intense LSD concerts. The first time I ever dropped, we went to see Savoy Brown. I was next to the stage in a very small venue and will never forget Chris Youlden in his stars & stripes coat and top hat and cigar. I had Peter Max visions and their music in my head all night. A great trip.
The second, we thought we were going to see Al Cooper. The Super Sessions lp had just come out and we were pretty geeked. Lo and behold, it was
Alice Cooper. We came out of that concert covered in chicken feathers and pretty freaked out, but I became an Alice fan after that. He was just so outrageous for the time.
The last concert, I don't even know who played. That's not the part I remember. I freaked out about half way through; the only time it ever happened to me and I tripped every week for a couple of years. We had a great source back then, straight out of CA (Sandoz). This time, we got it local. Pretty sure it was laced with something else and I was in pain and very paranoid. And, we were with some people that were, as we said in the day, really bogue. My friend got me out of there and the rest of that night was so freaky; major hallucinations. But, once I was away from the people who were giving off such negative vibes, the night turned out pretty fun. Just shows you how the right atmosphere can make a difference.
And this is where I bring it sort of back on topic.....I think the right atmosphere is really important when getting buzzed, especially when you get more buzzed than you anticipated or it's the first time. When people do edibles, they don't know what to expect; how strong it will be, what it's like, etc. If you feel comfortable in your surroundings and with the people you are with, it helps tremendously.
