The Mountain Goats is a band centered around singer/songwriter John Darnielle. They are an indie folk rock band with a reputation for lo-fi, heartfelt music, which in this case means music that they actually feel something about, rather than the cultural appropriation of heartfelt meaning maudlin.
“The Best Ever Death Metal Band Out of Denton” is a wonderful story song about 2 guys who dream of stage lights and music and have their dreams crushed by the people around them and resent it, because they weren’t allowed to try and fail, they just weren’t allowed to try at all. And the anger of the protagonists in this song is what makes it wonderful to me. Because it’s an honest human reaction in a song from a day and age of songs about people who react out of expectations rather than out of what they genuinely feel.
