Metal on Metal (Bastard) Video

Don't know too much about this lot, have a look at the video, and decide if you want to google them.
I for one, enjoy a crazy ass video once in a while (not as much as the crookers do), and if someone posted this on Facebook...I'd click the 'like' button.
Not sure if the Olympic comity have decided on this for 'the games', but it certainly has my vote.
