With songs like the dubstep-influenced "Radioactive" dominating the airwaves, you might not expect an Imagine Dragons cover to consist simply of three strings: a violin, a cello, and a double bass.

Classical trio Simply Three took that challenge head on with their recent cover of Imagine Dragons' "Demons," and it's incredible how the same song can take on such a different sound under their bows.

This passionate version is "simply" tops.
