Music discoveries

Ok so this next post is not neccesarily an unknown song but more of an unknown music video to the song, featured in Call of Duty: Black Ops 2, this coming from a game I played extensively online for years and consider my favourite online multiplayer version of call of duty, this is avenged sevenfold singing "carry on" this was part of a rather bizarre easter egg video after completing the game featuring all the games characters rocking it out together in a live performance of the song, the drummer being the hero of the game and the guitarist being the bad guy in their elder years.
