This got posted last week, but yesterday it started showing up everywhere.  It's a cover of AC/DC's "Thunderstruck" ... on two cellos.  And it goes HARD.  

It's by two guys named Luka Sulic and Stjepan Hauser, who call themselves "2CELLOS."  They've done covers of other hard rock songs before, like "Welcome to the Jungle" and "You Shook Me All Night Long".  Classical music lovers, be prepared for scenes of violent cello abuse in the video.

Here's the single on iTunes.
