Croatian cellists Luka Sulic and Stjepan Hauser, collectively known as 2CELLOS, rose to fame after uploading a video of themselves playing Michael Jackson's "Smooth Criminal" on their cellos. They've since signed on to record label Sony Masterworks and, last July, released an album with covers of songs by Kings of Leon, U2, Coldplay, and more.

Listen to their spine-tingling version of Nirvana's "Smells Like Teen Spirit" below.
