First Aid Kit @ The Enterprise, London, 23 Feb

First Aid Kit are a pair of Swedish sisters aged 15 and 18. They play enigmatic, stripped-down folk, and much has been made of their seemingly world-weary take on life: old heads on young shoulders and so on. Preconceptions therefore come easily as the band take the stage in this tiny room above a pub in Camden, which is already heating up uncomfortably in the way that only tiny rooms above pubs can.

But any glib put-downs like “shouldn’t you be at school” are quickly blown away by the sheer depth of the performance. The quite remarkable voices and psychic harmonies these two deliver, sparsely enhanced by simple strums and delicate keys, make it a difficult job to reconcile what you’re seeing with what you’re hearing. When the sisters sing “you don’t know what it’s like, to work from nine to five”, you can’t help thinking: “Well, neither do you.” But close your eyes, and it could be Loretta Lynn or Odetta Holmes, Grace Slick or even Bjork. They wear their influences childishly yet charmingly on their sleeves, peppering tonight’s set with covers of Dylan, Cash and even Fleet Foxes. But it’s impossible not to be transfixed by the haunting and ethereal aura First Aid Kit give off. The rapturous reception this crowd gives them suggests it won’t be long before they grow into quite an act. [Euan Ferguson]
