Deafheaven’s monolithic second LP Sunbather, was not only a massive success in 2013, it created a radical shift in heavy music culture, an acceptance of the genre by previous outsiders, and a trailblazing sound that heretofore hadn’t been heard outside of learned circles. It was a reville introducing the changing of the guard in metal, featuring phenomenal reviews across the board, and breaking the mold used by buttoned-up indie types and false-flag musical dilettantes intent on keeping the status quo.
