Phoenix based A Dark Halo sounds like Metallica meets Linkin Park with a symphonic touch and without the rap, this 8 track EP really took me by surprise how well produced it was. This electro metal could be used to a soundtrack, there?s a certain movie vibe going through these tracks. "Catalyst" is a package of keyboard driven industrial numetal also close to bands like Destrophy, Opiate For The Masses and Suburban Tribe. You?ll get a varied sounding EP all from the straight and classic metal of the closing track "Unbreakable" to the synthpop metal of "Silence". I just love the synthesizers in the progressive school of rock on "Nucleus", what a song!
