Anger can be such a useful emotion at times, and angry music can be a great motivator. Of course, in our day and age, most angry music is yelling and screaming a la Rage Against the Machine. I’m not opposed to yelling and screaming music; however, that sort of music tends to be hot anger.
On the other hand, cold anger tends to be rarer, so I appreciate it when I see it. Like this song, which is about a factory fire in Fall River, Massachusetts on September 19, 1874. Melodic, yet furious.
