Straying from the path and why it's good

The picture above is of the band Deafheaven (whose album Sunbather I reviewed here) and they have recently been convicted of a major crime, a crime punishable by a lifetime of ridicule and being mocked relentlessly. What did they do wrong? What kind of heinous crime was committed on their part to justify punishing them with such a sentence?

They fused black metal with post-hardcore.

Deafheaven-Sunbather ALBUM REVIEW

My interest in USBM (United States Black Metal for the uninformed) has been relatively high ever since I became a fan of Wolves in the Throne Room and Krallice as a high schooler several years ago. These bands, who showed up during the middle of the last decade, gave my generation its own black metal bands to sacrifice cats to, as well as freed us from being limited to just those scary-looking (or silly-looking depending on how you see it) 1990s Nordic fellows for black metal enjoyment. For me, this is fantastic because of how far-removed black metal seemed to me for such a long time. While I indeed enjoyed Emperor and Immortal, there wasn't a lot to relate to other than a distaste for Christianity. With these new trailblazers within our borders, I finally feel like I can take black metal music as my own, rather than just looking at it from behind a glass at a museum.
