Metal Ground was running a series of videos: Pop Singers VS Metal Singers, and a clip from this performance was used to highlight one of the greatest voices in all of Rock & Roll, and certainly all of Metal. Tarja. (They may still be running that series...)
This song is "Supremacy" (Live in Milan) by Tarja from a concert on November 29th, 2016 at the Teatro della Luna (Theater of the Moon) in Milan, Italy. It is included in the 2018 album Act II. It was originally written and released by the English rock band Muse in 2013.
Here's a link to the lyrics. She may be singing in English, but sometimes that doesn't help.
