It is hard to write a compelling 33 minute song, especially if the song features a handful of repeating guitar riffs extending ad nauseam. Remarkably, this is exactly what the Southern California-based sludge metal band Black Sheep Wall have done with the song “Metallica.” The song is of their 2015 album I’m Going to Kill Myself, which features memorable album art of two colorful monsters, as if out of a children's book, with one telling the other “I’m going to kill myself.”
