SCP Foundation

Sandbox link

First posted this draft a few weeks back, got some good advice and edited it since then. Looking for feedback on the new version. I tried to cut down on extraneous info while still keeping the background I wanted for the item. Specifically, I'm wondering how I'm doing with implications; if certain things aren't clear that need to be, or if I state some things too plainly, please let me know.

Since I'm still new to this site, I don't know how much editing has to (or should) be done before I can post this to the site. If anybody could provide some pointers on that, it would also be appreciated. Thanks in advance for your help!

Honestly, I had to look up the "So you want to be a critic" guide again because I didn't know how to respond to such a stellar scp. I love this in every way, and as much as I tried, I really couldn't find any major mistakes. A failed SCP experiment is always welcome, and the UMMAGUMMA event was a really welcomed twist in my opinion. I'm extremely impressed by this, and hope that I'm able to see this on the main list soon.

Edit: Post-extremely impressed nitpicking: Possibly the only thing I found confusing towards the end was the extreme amount of overdoses. Personally I'd dial down the double digit redacted number you got there. One more thing is that I think you should add something more about why they want to see the end of the concert so badly. Was the UMMAGUMMA event something you thought of after and added on to the end of a draft?
Once again, wonderful draft my guy, good luck!
