The Agit8 ONE campaign, which works to end poverty, is in full effect. Scottish rockers Biffy Clyro are the latest to participate in the campaign, covering their favorite protest song -- Rage Against the Machine's 'Killing in the Name.'

The band added their own touch to the song, slowing it down, so much so that you won't know what song it is until they started to deliver the lyrics. Frontman Simon Neil even warned the audience that they might not recognize the song until that point and he was right. It's almost unrecognizable in stripped down and acoustic form ... at first.

Even though the tempo is slowed down and the performance is more laid back than the incendiary original, the power of the message and the lyrics can't be muted. Biffy prove that a protest song doesn't always have to be fire and brimstone in order to get the message across, it can also be effective when delivered in quiet, measured tones, since it forces you to pay attention to what's being said.

Some of those Zack de la Rocha lyrics you might have initially missed amidst Rage's killer licks pack as much of a punch as ever in this setting. It's certainly an interesting and decidedly different way to cover such an in-your-face song.
