One Man Army and the Undead Quartet was a Swedish band, that played a fusion of melodic death metal and thrash metal. The band was formed by vocalist Johan Lindstrand after the breakup of The Crown. After two albums on Nuclear Blast Records, they moved to Massacre Records. Their third album, Grim Tales, received lukewarm reviews.[http://www.lordsofmetal.nl/showreview.php?id=12720&lang=en Review of One Man Army and the Undead Quartet, Grim Tales], Lords of Metal, November 2008[http://metal-archives.com/review.php?id=214731 Review of One Man Army and the Undead Quartet, Grim Tales], Metal Archives
