Avicii's video for 'Hey Brother' explores small town life and family relations, and the effects of war on the family unit and beyond.

It reminds us a bit of 'Stand By Me,' as two young boys from the '50s or '60s explore life along train tracks and spend quality time with one another. One is older than the other.

Life changes when duty calls and one appears to embark on a military career.

The nature of the relationships in the video is not 100 percent clear, but the footage, namely of the little boy holding the folded flag, are powerful and encourage further thought.

So does the stone-faced stare of Avicii himself at the end of the clip.
