2Cellos are turning heads once again. The duo, who previously delivered a blistering cello performance of AC/DC's 'Thunderstruck,' have now given a fresh spin to Iron Maiden's 'The Trooper.'

You can call it a cello mash-up, as the pair start their performance with a stirring rendition of the 'William Tell Overture' before segueing into the Maiden classic. As you can see above, the duo of Luka Sulic and Stjepan Hauser have shot a video for 'The Trooper Overture' and it takes a humorous look at the expectations of a rock show.

In this clip's beginning, the 2Cellos guys spot a flyer advertising a show stating, 'Want to Be a Rock Star?' As they approach the stage with their cellos, there's a certain amount of unrest from the unruly rock crowd before they start showing the power of their instruments with the 'William Tell Overture.' One by one, the audience members are transfixed by the performance and by the time the duo switch things up to 'The Trooper,' everyone is rocking along.

Iron Maiden even commented on the performance, posting on their Facebook page, "This is a pretty sweet cover."
