The Dreijer siblings return, bringing their twisted and pulsating electronica to London for another date on their 'Shaking The Habitual' tour. Their date at the Roundhouse last year split opinion for featuring almost no live music; instead the band and their dancers hosted something resembling a mass aerobics class-slash-rave. Space cults, gender politics, glitter and drums also featured heavily. Will they revive that here or do something completely different? As ever with The Knife, it's hard to be sure – but chances are that whatever they do, it'll be spectacular.
