The cheesiest of the cheesy right here, so gloriously awful. I love it. If you haven't yet enjoyed their first album, and you are a fan of cheesy power metal, do yourself a favor and indulge.
I actually really love Deafheaven. That perfect mixture of Shoegaze and Black Metal is something I never really was a fan of until I heard Sunbather. There's not a lot of other bands with similar style that I really liked yet.
Plus it pisses off all my black metal friends when I call it black metal, so that's a bonus.
