Machine Head played a secret show in London last week, under the name Ten Ton Hammer...and in addition to a set loaded with covers of songs by bands like Poison Idea, the Foo Fighters, and System of a Down, they performed their own song "Pearls Before the Swine," from their latest CD Unto the Locust, for the first time ever. Check out the video above.

Unto the Locust is available now in the Roadrunner webstore.
