Alexisonfire is a post-hardcore band from St. Catharines, Ontario, Canada. Their music is characterized by turbulent and explosive dynamics with intricate guitar melodies. Consisting of five friends, they formed in late 2001. The band's name is a sort-of homage to a contortionist stripper named Alexis Fire. Band members include George Pettit, Dallas Green, Wade MacNeil, Chris Steele and John Hastings.
In December 2012, Alexisonfire will perform a series of Canadian concert dates as part of a final farewell tour.
