Replying to Skrillex is fake?

I saw 12th Planet, Skream and Benga, Nero, and Skrillex the other night for the spooky tings in denver. Already seeing Skrillex, I knew he wasn't very good at mixing and Nero and Skream and Benga killed it so for the Skrillex show I went to the back of the venue to just chill and watch the cell. While back there, I noticed 4 Scandinavian guys IN TINFOIL HATS (keep in mind it was Halloween night, but tinfoil hats, really?) playing Skrillex's entire set. While Sonny Moore had his hands clapping in the air, these guys were mixing 4 songs together. I watched them play the entire set mixing every song together and they had the track lists in front of them whole deal. These guys were truly DJing, while sonny moore was doing some whomp dancing. So now my question is, are these 4 random guys the REAL skrillex and sonny moore is just their front man, or did skrillex blow up too quickly and he couldnt handle the pressure, so he created the cell to have other DJ's do his work?

REGARDLESS

Skrillex WAS NOT playing his set when I saw him, instead four Scandinavians in tinfoil hats were mixing all of his songs together while he danced on stage.
