The duo's piano/cello mashup of David Guetta's Titanium and Faure's Pavane is up for Response of the Year in the first ever YouTube music awards, alongside Lindsay Stirling's Radioactive.
The YouTube Awards celebrate established artists including Lady Gaga and Miley Cyrus as well as lesser known performers, in a range of categories marking the most fan engagement, the most watched artists, the most fan videos created, and the artists with the biggest growth in views and subscribers.
Titanium/Pavane and Radioactive feature in a category alongside Jayesslee's remake of Gangnam Style, Boyce Avenue's Mirrors, and Walk Off the Earth's I Knew You Were Trouble.
Lindsey Stirling is confirmed to be performing on the night, alongside performances by Lady Gaga, Eminem, Arcade Fire, Avicii, and M.I.A. The ceremony will take place on November 3, and will be streamed live online.
