The sounds I heard were 10 feet away from the compacted wall of people stuck on top of each other burning and screaming. The only thing I can imagine is a higher quality version of it from a different angle, because the screams are incredibly clear in the video I saw, albeit you only see up close for 10 seconds total. I remember you can see the people trying to claw their way out over each other while they scream from being burned from behind.

I also saw video and audio from inside the club as it starts to go up and everyone gets gummed up in the exits.

All to say I think it's crazy someone just goes "Yeah everyone go check the video out!", when I objectively know it's in the tip top of horrific video. The screams you hear there are honestly more than you hear in a cartel video.
