A decibel-crushing Southern California metalcore outfit with grunge and nu-metal influences, Of Mice & Men were formed in 2009 by ex-Attack Attack! vocalist Austin Carlile and New Zealand-born bass player Jaxin Hall. The group broke into the hard rock mainstream in 2011 with the release of their third full-length outing, Restoring Force, which marked the debut of clean vocalist Aaron Pauley. Pauley eventually took over vocal and bass duties from Carlile, the latter of whom left the fold in 2016 due to health issues. The group continued to dole out powerful LPs through the end of the decade, including 2019's Earth & Sky and 2022's Echo.
