The Brothers Highhorse's newly released single "A Graveyard for Lunatics" is roughly four minutes long. They combine some elements of black metal, mostly heard in the vocals, with standard deathcore. The pace of the song is fast, and the instrumentals change through the song. In the beginning to about midway through, they have a fast-going death metal sound, then transition into a more melodic one for a small amount of time. However, quickly transition back to the fast-going death metal sound with symphonic elements for the rest of the song. The vocals used are black metal-like high screams and low screams.
The only thing you can notice about this song right away is the poor audio quality, and I think that takes a lot away from the song itself. If the band were to release a new song in the future with better audio quality, I believe it would sound a whole lot better. Other than that, it is a solid song with variety.
