There's a husk to Daughter's voice tonight, a cracked, bluesy tone that's marvellously subtle. “I'm, er, feeling, quite nervous,” she says, taking the stage, “this is the biggest gig we've ever played.” A field of boys in the audience peer up from the barrier and fall instantly in love, as her charm becomes a constant feature to tonight's performance. We later come to find out those two days ago, the girl we watch in such admiration was without a voice, battling illness to perform the final few shows ahead of four months of recording.

The gig is billed as an acoustic affair, a term that support band, Theme Park, take quite literally, staggering onstage to a maze of bongo's and acoustic guitars. The set feels frail, as vocals crack under the tension of the highly strung bongo beats, and the boyband style chairs don't help the whole charade. I highly doubt the One Direction look is what Theme Park is aiming for. Regardless, there's no doubt they'll be a band to watch this summer, but in the stuffy surroundings of Islington Assembly Hall they feel unassuming.

Tonight is many of the audience's first experience of seeing Daughter live, so the whole affair is a studied one. There's a pressure to the room that makes it feel less like a gig, and more like an episode of Britain's Got Talent, which as we know, is NEVER good. But the fans are supportive and smother Daughter in applause at every possible moment.

The pound of bass races through the hearts of the audience, as heavy sound gives Daughter the depth her tracks so crave for. But, the crowd feel stagnant at first, probably more through adoration that a crippling inability to dance, but it makes the room feel ever so slightly tense, especially as Daughter stumbles a little at the start. It does all come to though, and by the end, the audience sing in choral to a teary eyed band.

I spend most of the time wanting for more, because I'm tricky like that. Daughter's brilliant, magnificent even, but on the whole the live performance feels lacking. Whether it's the connection between the band, or the sheer velocity of sound I expect, i don't know. But this feels withdrawn. A new track towards the end feels stronger, though. While beautifully melancholy, it drowns in the power of a throbbing amen break that splits the vocals up perfectly. There's a viciousness about it that won't be expected, but it just proves that Daughter's got the velocity in her voice to carry as a major performing artist. It's just how she takes the next step that's going to be the important part.

The gig ends, and regardless of what I analyse to write this review, I leave in emotional turmoil. Damn you, Daughter, you heartbreaker, you.
