In a special solo performance in the beautiful North London church, the revered singer-songwriter played songs from last year's B-sides & rarities collection Phases, as well as a glut of new material.

The chapel’s breathtaking setting - and perhaps some classic British over-politeness - renders Olsen’s audience mute. In return, she amps up her characteristically acerbic sense of humour. “I might add a piano part, or a guitar solo, I don’t know”, she notes after playing a haunting new number. “Consequence of Sound or Pitchfork will know. They can suck my dick”.

Although her raucous and self-deprecating monologues between songs certainly livened up the room, her performance of each tune, from Phases’ “Sans” to favourites “Unfucktheworld” and “Windows”, exposed the truly miraculous breadth of her vocal range. In a performance that made the most of Olsen's dazzling new material, this was a haunting and intensely intimate experience delivered by a singer at the top of her game.
