Alan Walker, Norwegian with British background, just turned 20 and a few years ago he wouldn't even have thought about being the most successful Norwegian artist in history. His singles and videos are one of the most watched and most listened to on YouTube - over 8.7 million subscribers on his channel and over 2.5 billion plays.

In his documentary series titled "Unmasked" we get insights into his work: how he creates melodies in the studio, how he started with music in the first place and he even shows us his hometown Bergen!
