…that's Arcade Fire to you and me. Under a cheeky pseudonym, the Montreal collective play their smallest London shows in years in support of their new album 'Reflektor'. They've added a dose of disco and an even bigger dollop of weird to the large-scale, layered and thrillingly uplifting orchestral pop of their early albums, and they'll be showing it off tonight with what should be another dramatic, euphoric live spectacle. 'Formal attire' or a costume is mandatory, as at the band's disco-inspired recent New York shows. Beg, borrow or steal tickets: this'll be one of the gigs of the year.
