My favorite female trio right now. I discovered them through the Eurovision song contest where they performed in 2019 as background singers for the Swedish entry by John Lundvik:

In 2020 they had their own entry for Sweden: Move, but Eurovision 2020 was cancelled due to covid.

For Eurovision 2021 they are in the final of the SwedishMelodifestivalen 2021 so they might be the swedish entry this year.
