"Livewire" is a track by a 2 piece called Oh Wonder.
They're a fairly new asset to the music industry, only forming in 2014 but have made a massive impact during their short tenure. They've been releasing one song a month for a year since last December I believe.
This song is a fairly new one in the circumstances and definitely one of my favourites. Their sound could be described as art pop/shuffle pop, containing simultaneous lead vocals from Anthony and Josephine - never really harmonising in the common sense of the word, just singing an octave apart from one another. It's a really great sound and I can't really recommend them enough, they've had quite a bit of radio airtime especially from BBC Radio 1.
P.S - I've got a couple of spare tickets for their Bristol show if anyone would like them!
