Judging by the lack of the responses... nope, no one's tried this. I can see why, too; mescaline isn't something I'd consider a real party drug, it's quite mellow and smooth and has a very particular, gentle atmosphere to it. It's really meant for a more spiritual atmosphere.
I have had a very low dose experience of mushrooms at an electronic music festival and it was brilliant, I'd do it again for sure. But hey, maybe try it anyway, I'm sure it wouldn't be a bad experience by any means. Have you taken mescaline before?
