Rockers pulling up to the show this Sunday have been sent an email about dress attire ahead of the performance.
It comes as the metal band are known for wearing iconic masks and are known for their punk styled army of fans.
Now the venue has informed revellers that certain items are banned from the show and will not be allowed inside.
This includes fashion statements like large belt buckles and chains longer than 30cm.

Spiked items such as shoes, jackets, belts, and bracelets are also not permitted at the performance.
The email states: “Items (including clothing) that may pose risk to others are not permitted within the venue.
This includes but is not limited to; large belt buckles, chains longer than 30cm, and spiked items.
“Masks/face coverings of any kind are welcome in the standing/seating areas, but must be removed during entry and while in the concourse/public areas of the venue.”
Fans were quick to respond on social media to the dress code.
One fan said: “I’ve been going to The Hydro since it opened and that’s the first time I’ve seen rules like that before, next they’ll be saying no phones allowed.”
A second fan said: “I got this warning and it’s the first email like this I’ve ever got. Seen Slipknot in there a few times and never had that!”
A third fan said: “No spikes or chains? Do they know who the clientele is?!?”
A fourth fan said: “This isn’t something new. Be to do with health and safety and people not getting injured off the spikes. It’s b******* but sadly they don’t want to be liable.”
