It is at the SAGA festival.

There were invited many singers,one of them being Alan Walker.

Alan Walker is a norvegian music producer.He plays the electric-piano and doesn't really use his voice to sing,but rarely.He just plays the music while he has someone to sing the lyrics.

He wears all black,a hoodie and a mask covering his lower part of the face.

He has made music with many different people,both friends and other singers.

He is polite and friendly with everyone,and vice versa.He is also making jokes whenever he is on stage,just to lighten the mood.He apologizes whenever something is his fault and makes sure to make up for it.

After he performs on stage,playing the electro-piano while a singer sings,the singer thanks him before walking off the stage.

Right now,the concert is going.

Sofia Carson is singing the song Different world while Alan Walker is right behind her,playing the electric-piano.

(You're Alan Walker.)
