If serenity and flamboyance could co-exist, it would be on stage of a First Aid Kit performance. The sisters duo of Johanna and Klara Söderberg are one of my favourites for this reason.
Photographing their show is like lying in wait for a grand fireworks show. One moment, you are admiring stars on a clear blue sky and then out of nowhere, boom; the sky lits up in fiery colors.
I once drove 500 km to spend 15 minutes photographing their show and drove back. It was worth it!
