2CELLOS' Cover Of AC/DC's 'Thunderstruck' Gets More Than 5 Million YouTube Views

Video footage of Luka Sulic and Stjepan Hauser, the Croatian cello duo known as 2CELLOS, performing a cover version of AC/DC's "Thunderstruck" can be seen below.

2CELLOS became an overnight Internet sensation with their self-made music video of themselves performing MICHAEL JACKSON's "Smooth Criminal" on their cellos. Within days "Smooth Criminal" racked up over five million views on YouTube, and legend Elton John invited them to join him on his tour.

"We always try to put our own spin on it, do something different with the song and present it to the people in a new and fresh way," 2CELLOS told GoodMorningAmerica.com. "We try to add an extra classical dimension to those well-known evergreens through our cellos."

Hauser added: "We cover songs that we love and we play music that we are passionate about. These songs have to mean something to us, and of course, they have to sound great on the cello."

Luka Sulic and Stjepan Hauser have been playing the cello since childhood. Both completed their studies — Luka at the acclaimed Royal Academy of Music in London, Stjepan at the Royal Northern College of Music in Manchester. Luka has performed throughout the world at renowned venues such as London's Wigmore Hall, Amsterdam's Concertgebouw, Vienna's Musikverein and Konzerthaus. He has won a series of international prizes including first prize at the 2009 VII Lutoslawski International Cello Competition in Warsaw. Stjepan has performed in numerous European countries, South Africa, New Zealand, Asia and the U.S., with debuts in London's Wigmore Hall, Royal Albert Hall, South Bank Centre and Amsterdam's Concertgebouw. He was the last pupil of Mstislav Rostropovich. In his short career, Stjepan's accolades include winning twenty-one first prizes in national and international competitions and performing twice for Prince Charles in Buckingham and St. James's Palaces.
