Two Croatian cellists are taking the internet by storm - with their version of AC/DC's heavy metal classic Thunderstruck.
Luka Sulic and Stjepan Hauser are known for covering songs that you wouldn't normally associate with their instrument and in the past have covered Guns 'N Roses and Coldplay.
But their latest revision of AC/DC's classic hit could be their most impressive yet.
The Croatians, dressed in 18th Century clothes, rocked out in front of an audience that seemed more than a little startled by their performance.
