In late 2014, Machine Head was all set to launch a big North American tour alongside Finnish heavy hitters Children of Bodom and rising Dutch band Epica to coincide with the release of the highly anticipated new album, Bloodstone & Diamonds. It had all the makings of a successful tour; after all, Children of Bodom easily sell out venues on their own, so to have them opening would only make the demand for tickets even higher. But less than three weeks before the tour was set to begin, Machine Head pulled the plug on the entire thing, apparently because the new album wasn’t even finished yet. That rubbed a lot of people the wrong way, especially those in the Bodom and Epica camps, who had gone through a tremendous amount of preparation and paperwork to bring the European bands to North America. Bodom frontman Alexi Laiho took to Facebook to express his displeasure, Machine Head’s Robb Flynn responded, and things got very ugly very quickly.
