Greta Thunberg's UN speech has been turned into a Swedish death-metal song

A New York thrash-drummer was so moved by the Swedish teen's speech, he picked up his sticks and created the viral video.

Swedish climate activist Greta Thunberg's famous UN speech has been turned into a viral death metal hit. 

The visibly angry teen berated world leaders at a climate summit last week, accusing them of betraying her generation by failing to tackle greenhouse gas emissions and asking "How dare you?"

The music in the clip was written and performed by drummer John Meredith from the New York-based Indonesian thrash band Suaka.

He told the Rolling Stones: "the words she chose just evoked the darkness of the metal music I love: Entombed, Gojira, At the Gates, Sepultura."

Mr Meredith is also a recording engineer and owns the Mollusk Studio in New York. 

Even the 16-year-old activist is a fan of the metal makeover, with Ms Thunberg jokingly posting to Twitter she'll only do death metal from now, to which Mr Meredith offered to perform live alongside her.

Other renditions have since been created, including a "Dark Spektor Baal Synthwave style" by YouTuber Spektor Baal.

"Hearing the speech reminded me of the movie 1984," the YouTube magician said.

"This is an art piece."
