Entertainment conglomerate Disney has reportedly pressured a promoter to move a show featuring Machine Head, Throwdown and others due to concerns about "violent imagery, undesirable fans and inflammatory lyrics."
The bands issued a statement:
While the enactment of this new blanket rule applies to all upcoming heavy metal shows at the House Of Blues Anaheim (with some metal bands having been banned from performing on name alone), Machine Head is the first band to actually have tickets go on sale, and remain on sale for 2 months, before intense pressure and vague threats of liability from the Corporation left the promoter with no choice but to remove the show from the venue.
The show was eventually moved to an alternate location and will take place in Pomona rather than Anaheim. You can find the full statement here.
