On the night of August 2, 12-year-old Adriana was murdered in Norsborg south of Stockholm.

When the music festival This is Alby is held this weekend, just east of Norsborg, 14-year-old Lilly L is on stage.

She describes Adriana as a little sister and says that even though she thinks it feels fun to be on stage, it "cuts like a knife" to talk about her friend.

- I had a lot of stage fright and singing for people and so on, so she always said "please can you sing" and always when I sang, she danced.

I just wanted to make a song for her because I know how much she loved when I sang, she says.

Cherrie, Jireel, Imenella and Haval also perform at This is Alby.

PSL has met Lilly L, see a longer interview here.
