This is one of the better demos any band has sent my way. Valve mashes sludge and post-hardcore together to great effect. I like sludge, but I can’t sit through a full sludge album or sludge set without being blazed out of my mind. Valve tempers the creepy slow crawl of sludge with odd chords and guitar tones. Throughout the demo Valve manage to temper metal chugging with prog-rock guitar runs and well-timed break downs. Their singer utilizes a very raspy tone that fits the tunes well and doesn’t overpower the music. He also has a pleasant clean singing voice that fits the less heavy sections beautifully. Its a sweet Demo by an interesting up and coming band.
