2CELLOS Leave You Thunderstruck
You probably aren't sure how to feel about this, but rest assured, this video is well worth a few minutes of your time. Two guys who perform together as 2CELLOS released a video set in what appears to be an 18th century opera house. They begin with traditional orchestral fare but turn things upside down with their amazing cover of AC/DC's 'Thunderstruck'.
The version is edgy, menacing, intense and AMAZING.
