Lily Rose Thomas's video for electronic duo Ider explores what it's like losing part of your identity when going through a break-up - and not recognising yourself in the mirror.

Her method is to have both bandmembers, Lily Somerville and Megan Markwick, performing seperately in the same situations, side by side in split screen. It shows that both have considerable charisma, and the effect is powerful.

And just when you're used to the split screen technique, Thomas mixes it up to show that these girls really are stronger together.
