Tantara, a Norwegian thrash metal band from Vestfold, was formed in 2009 by Stian Sannerud and Fredrik Bjerkø. The duo transformed their project into a full-fledged band with the addition of Per Semb and later Bjarke Haakenstad. In 2010, Tantara released their first demo Demo 2010 and EP Human Mutation. After Haakenstad's departure in April 2011, Max Warnby joined the band as bassist. Their debut album Based on Evil, recorded under Flemming Rasmussen in Copenhagen, was initially planned for release in 2011 but was eventually released in August 2012. The album included the single "Based on Evil". In 2018, Tantara released their second studio album Sum of Forces.
