2012–2013: Formation, ''Demo 2012'' and ''Worse Than Dead''
Iron Reagan originally formed in 2012 and consisted of members Tony Foresta of Municipal Waste, Paul Burnette formerly of Darkest Hour, Phil Hall of Cannabis Corpse and Municipal Waste, Mark Bronzino formerly of A.N.S. and Ryan Parrish also formerly of Darkest Hour. The name of the band is a pun on the heavy metal bandIron Maiden and the 40th president of the United States, Ronald Reagan. That year, the group released their first demo, Demo 2012, through Tankcrimes Records which featured the tracks "Pay Check", "Eat Shit and Live", "Artificial Saints", "Running Out of Time" and "Walking Out". The first two tracks went on to be featured in their debut full-length album. On March 20, 2013, the band released their debut studio albumWorse Than Dead through the record labelA389 Recordings. It was produced by guitarist Phil Hall. The album received a score of 5 out of 10 by Exclaim!, saying, "they're basically indistinguishable from their singer and guitarist's main band. Iron Reagan are rounded out by ex-members of Darkest Hour, but their influence isn't nearly as prominent as the crossover thrash of Municipal Waste." Bassist Paul Burnette left the band and was replaced by bassist Rob Skotis of Hellbear.
