Due to getting the Download headline slot a couple of years back, they've really worked on their live show as a spectacle and i think would be pretty bloody excellent as Other headliners, in the dark. Last time they played they were opposite Kylie in the legends slot, which didnt help them - and in 2016 half-clashing with zz top, which i'm sure didnt help them either with tons of crossover in the fanbases - so an Other headline spot with not much crossover would see a huge great big crowd, i'd say. Great alternative to whichever is the most pop-friendly pyramid headliner
