The Fire hitmakers will celebrate their 10 years in music with the special gig at Victoria Park in Leicester, England on 21 June (14).
The concert will mark a decade since the band released its self-titled debut album in 2004, and guitarist Pizzorno fears fans will be whipped into such a frenzy by the occasion that they will need to let off steam afterwards with a destructive rampage.
He tells rock magazine Q, "God bless the council. I don't think they realise the city centre's gonna be a war zone. Cos we're gonna just rally this crowd into such a frenzy and then go, 'Right, that was it.' And everyone's gonna go, 'What next? Riot!' I hope it's a love-in. That's what I'm praying for."
