In 2009, singer Austin Carlile left Attack Attack!, teamed up with bassist Jaxin Hall and formed Of Mice & Men. However within a few months, Carlile and Hall had both left the band and Jerry Roush was recruited as their new vocalist. He didn't last long, as nine months later, Carlile returned to the fold and Roush was out. Despite a few more tweaks to their line-up OM&M pulled together for the brutal assault of post-hardcore and crushing metal on 2011's The Flood.
