What music video is this?
 

Hi. Maybe you guys would help me. I'm looking for name of the vocalist and the title of a song, yet i remember only the videoclip.
I think it may be a song from 2011 or 2012, vocalist is a girl, brunette with long curly hair, probably English. Videoclip is in tunnel, where she is shown singing. Some parts of this clip are made as stylized frame-by-frame animation with contours ripped out from gazette. It's not so unknown song. Any ideas?
