Why has this band been "black listed?" The riffs are pure intense shred. There are killer solos. For a "grind" associated band, they are considered "metal" amongst the "grinders." Most grind bands do not have such intricate riffs, harmonies, and solos. Like extreme death metal, there are brutal vocals of a wide range, and blast beats galore. Here are some examples of the music and the albums for sale.

Blacklisted in 2017 for being more on the punk side. These albums sound more metal, so they're worth re-assessment. Go ahead.
