American Dasha got her breakthrough with the song "Austin", which quickly went viral and has now been listened to over 400 million times. The finale of Allsången will be one of the star's first performances on Swedish soil.
"Some of my biggest fans are from Sweden, and I can't believe I'll finally get to perform for all of you", she says in a press release.
Henrik Dorsin, Vanna Rosenberg, and Johan Ulveson will also be guests at the finale on August 13, with a performance from the upcoming production "Svenska revyn", which premieres at Scalateatern this fall.
"It's very exciting to, in this Swedish institution that Allsången is, get the chance to perform a number from 'Svenska revyn' for the first time", says Henrik Dorsin in the press release.
It has already been announced that Miriam Bryant, Orup, and Isak Danielsson will participate in the program.
Corrected: An earlier version contained an error about how much Dasha has performed in Sweden.
