Since the release of "The Blackening" in March of 2007, Machine Head has toured incessantly, playing more than 300 shows in support of the Grammy-nominated album. And while this 3 year-long album cycle has seen Machine Head share U.S. and European stages as main support to Metallica, Slipknot, Slayer, Marilyn Manson and Megadeth, headline the Jägermeister stage on the Rockstar Energy Mayhem Festival, and headline the legendary Wacken festival to over 85,000 people, it hasn't seen them on a full-fledged headline tour, playing full-length sets.
