What's something the world has enough of?Game of Thronestheme covers, that's what. We've seen so many good ones over the years, it's hard to pick which one is the best.

But 2CELLOS, a duo of extraordinarily talented cellists from Croatia, have taken it to the next level.

In the first single from their new album, "Score," the duo -- Luka Šulić and Stjepan Hauser -- play a Game of Thronesmedley with the London Symphony Orchestra. The cover is subtler than some others we've heard, but there's a lot of authorship in it as well, with the two cellists performing some string acrobatics in the second part of the song.

The video for the song was filmed in the Croatian city of Dubrovnik, which was the main filming location for the city of King's Landing in Game of Thrones.

Two years ago, we had a chance to host 2CELLOS in our Mashableoffices in New York, so take a look at that performance as well.

The duo's new album will be released on March 17, and will contain many more cello/orchestra covers of popular film themes, including soundtracks from films such as Schindler's Listand The Godfather.
