The American rapper and soul singer guested with Avicii on the single "Wake me up" in 2013.
It has already been known that Nile Rodgers, Tjuvjakt, Seinabo Sey and Sarah Klang, among others, are ready for the concert on December 3rd.
"For a better day" is organized by the Tim Bergling Foundation, which was founded by Avicii's parents Klas Bergling and Anki Lidén in memory of their son to promote the mental health of children and young people.
This will be the third year the concert has been held in Avicii Arena. Artist Ida-Lova and comedian Christoffer Nyqvist will host the gala.
