The gig: Arcade Fire (Roundhouse, London)

What is it? The rock band take to the stage after the release of their much-anticipated new album, Reflektor. Fancy dress was mandatory, fans were told.

The Independent says: “It’s a measure of the potency and immediacy of this band’s music that despite Reflektor having only just been released, [the crowd are] totally familiar with all the riffs and hooks, bouncing and singing along.”

They say: Evening Standard: “Even with 10 musicians on stage and some pretty snazzy outfits among them too, Arcade Fire didn’t quite have the fire of old … arena dates to come should see more balance to the setlist and the band back to full power.”

The Quietus: “Arcade Fire could easily sell out a string of shows at a soulless stadium and bang out their greatest hits, but instead they’ve decided to … fanny around in giant papier mâché masks, and throw a bunch of smaller arty-party happenings …. You could argue [that] these theatrics detract from the music. But it swells in the right places with the epic grandeur that Arcade Fire does so well.”

You say: @GarmonRhys: “Arcadefire absolutely killed it at the @RoundhouseLDN last night. Sublime”

@mathewfenner: “Had the most amazing time at Arcade Fire last night, my heart is full ... now I need to re-evaluate my life”
