Following last week's rather dodgy looking poster leak, which ended up being confirmed by various sources (such as NME), and a million other possibly date rumours (Glasgow and Blackpool), it seems Arcade Fire will be playing two shows at the Roundhouse in London next month as The Reflektors.

According to the following tweet by the reputable ArcadeFireTube (via Best Fit), the band will play the iconic venue on November 11 and 12th. "Formal dress or costume" is required.

More information when we have it. Reflektor is out now.
