Sia is set to make a special appearance at Finland's Flow Festival next summer.

The Australian singer joins an already packed bill, with the likes of M83, Stormzy, CHVRCHES and more peppering the line up.

These are heady days for Sia, who is busy contributing to Rihanna's new album. The singer has found time to release her own single 'Alive', which came accompanied by some stunning visuals.

Check out Sia's performance on The Ellen DeGeneres Show below.

Flow Festival runs between August 12th - 14th.
