All music has themes but metal is a genre which wears its heart on its sleeve. Thematics color everything in metal, from audience reception and marketing to the actual composition and execution of the music itself. It can affect production, tone, scales, and much more in an effort to align everything with a perceived image or to jar that image by deviating from the norm in just the right way. Take goth metal; a sub-section of doom, it relies on the theme of autumn, death, depression and nature for its impact. We haven’t even mentioned bands yet and album art, track names and that certain goth sound has already sprung into your mind. Sometimes, these themes become even more powerful and, by some twist of fate or by a pecuilar predestination, reflect in the musicians themselves: they might reflect the ideals of the music in their actions or in the facts of their lives.
And sometimes, that reflection has a bitter edge.
