Please have a look at the first 15 minutes or so of Machine Head’s set from the House of Blues in Houston on Feb. 11, 2012. The band is currently touring ‘Unto The Locust,’ and though I personally preferred ‘The Blackening’ I have never seen them better live. Power just naturally flows from the band. They’re playing free and easy and are more deadly than ever as a result: effortless heaviness, the best of all worlds.
