^^Dont get me wrong I've had a few good nights out on MDA but overall it doesn't feel conducive for crowds to me. And this is coming from someone that has no problem taking true psychedelic drugs in the exact same setting. I absolutely love psychedelics too but for some reason MDA just feels like a low key gathering type of roll.
I have way more fun taking mdma and lsd or Mescaline if I want that trippy aspect and 8 times out of 10 I'll do just that. Mainly cuz I feel psychedelics allow for more fluid dance, especially LSD, and also provide a better afterglow.
Also I too have seen both Eptic and Excision. Good shows from what I remember (years ago.) You sound like you like bass, I assume you've had the pleasure of getting your mind warped to some Funktion 1's, if not I highly recommend. F1's and MDMA is the ultimate combo haha, I'll dance from 2pm to 6am every night if I got heavy bass music and some F1's I'll go until my legs start giving out on me.
To be fair looking back I've had some stellar nights on MDMA/MDA combo pills. Maybe I'm being a little hard on it, I guess over time it's less and less amazing at shows for me though cuz all of those were like 7-8+yrs ago.
Sorry OP to not answer your question though about trippiness. When you get tripping on MDA it's moreso a delusional type of trip vs the typical psychedelic warping what you currently see. You can really get lost in it but there's typically zero fear about this while it happens.
For me it's mostly been empathogenic but on the few occasions where I did trip on it (redosing MDA really brings out the trippy side of it) I'd see things that weren't there or not see things that I know should be there. Also peoples faces will warp (just like Mescaline) where you'll think it's so and so until they speak and you instantly realize it's someone else. This can make finding your friends late at night in a crowded venue somewhat difficult.
To give an example one time I was at a mini hotel festival rolling on MDA and MDMA (half n half). We went back to the room and when I went to go throw away something the trash can was nowhere in sight even though I knew deep down it was there. I blinked and it reappeared. Later that night I fell asleep but was woke up to the fire alarm going off (kids kept setting it off with smoke) and thought it was the thermostat for some reason. The first 10min I was calm trying my best to figure it out but I slowly lost my patience and after another 10min of me freaking out on the thermostat my brother woke up and told me I was nuts lol.
Good times
