Mosh pits at Twenty One Pilots shows are no joke.

The band interrupted their set twice in London on Wednesday when they noticed fans needing assistance in the pit.

“Bring up the lights on the crowd. Security, we have someone in the middle there that needs to come out. If we could try to make a split down the middle for someone back there to get to the front, please,” frontman Tyler Joseph asks calmly when he noticed a fan who needed some air.

About 15 minutes later, it happened again. “Security, we have another fan that needs to come out right here.”

Both moments play out at 51:52 and 1:03:10 in the fan footage below.

Twenty One Pilot’s album Trench is due October 5.
