Bryce Avary from The Rocket Summer :)
He was performing at the Slam Dunk festival at Leeds University.
Me and my friend were excited by the fact that they had a WHOLE SUPERMARKET in the university and wanted to take pictures of ourselves shopping with pints of beer (we're pretty cool like that) when we came across Bryce.
He is seriously one of the sweetest guys i've ever met, he said he remembered me from his show in Newcastle because of my hair (a lie i'm sure but sweet none the less). We stood and chatted for about 10 minutes but I started to feel awkward so I told him to have a good show and started to leave when he grabbed my hand, looked me straight in the eye and said "I'd really, really love it if you guys could come to my show". DEAD <3
His set was amazing, maybe even one of the best shows i've been too. He took requests from the audience towards the end and even had a little crowd surf. Basically he was brilliant :)
Edit: For those who keep asking who he is
