WHILE SHE SLEEPS is one of England’s greatest metalcore force. Their unique take on the genre has led them all over the world. This is the sort of high energy madness that serves to make the UK metalcore scene so vibrant. It’s impressive to see how far WHILE SHE SLEEPS have come in a relatively short amount of time – their debut album only dropped in 2012! Watch them bring the energy that won over the world at Hellfest!
