I yeah I don't think I'd trip, on either mescaline, lsd or shrooms while listening dark psy trance (from what I've heard of it, which is only 3 or 4 songs). The wrong music can be a nightmare. I haven't tripped in 5 years, but even back then I only did mescaline (peyote) and shrooms. We listened to Sasha+Digweed/Oakenfold and stuff of that nature. I don't even know how I would handle goa or full on Mortal Kombat psy trance, I would think ecstacy would be better for the faster, more crazy stuff. But I degress. Besides the occasional joint or cocktail, I don't get messed up too often at all.
