>>In early 2008, upstart English punk band Gallows was all set to open for Social Distortion at a gig at the House of Blues at
Disneyland. The bill seemed like a good way to get exposure for a band that was starting to catch on stateside—or it did until Disney officials actually stopped to listen to Gallows' debut record,
Orchestra of Wolves. Once Disney brass heard Gallows' tunes, they nixed the show due to the band's occasionally offensive lyrical content.
While it seems odd to get upset at a punk band for being abrasive, Disney's move wasn't unprecedented. Just a few months earlier, the company had banned the metal band Machine Head from performing at the House of Blues for similar reasons.<<
