John Knox Sex Club are a six-piece band from Glasgow, Scotland. They formed in 2008. In 2009 they performed at The National Portrait Gallery in Edinburgh, causing it to close until 2011 after inflicting severe structural damage. In 2010 they performed at House for an Art Lover, causing Charles Rennie Mackintosh to twist and shake in his grave. In May 2010 they released 'Blud Rins Cauld' from their home label, Last Blast. An 8 track record of their work to date, it was thankfully well received by both Edinburgh City Council and the Mackintosh Society.
