The concert is called Hela Sverige Skramlar, which translates to "All of Sweden is jingling". It's taking place at the Globen arena, which has been loaned out free of charge for the event.
The opening act will consist of 75 singers from the Tensta Gospel Choir, and Radio Sweden rang up the director of the choir, Cedwin Sandanam, while he was on his way to the venue, to find out how it's going to feel to step on stage.
"I'm really excited for many reasons," said Sandanam, who feels this is a good time to perform this kind of benefit concert.
"I think people are opening their hearts in another way," he said, adding that he recently read that anti-immigration sentiment has decreased.
After the Tensta Gospel Choir opens the concert, they'll stay on stage to accompany Carola and Ola Salo.
The concert begins at 7 PM and will be broadcast or streamed live by several different media outlets.
