There are few bands that deliver with the same intensity and aggression that thrash metal acts are inherently known for. Denver natives Havok seek to remind us why that is. With their third and latest album, Unnatural Selection, just released June 25 on Candlelight, the band is heading for Saint Vitus in Brooklyn on Aug. 7 and to Championship Bar & Grill in Trenton on Aug. 9. The album follows a consistent theme of anti-government views, and is heavily fueled by the lightning-fast lead guitar riffs and a solid rhythmic progression provided by the four-piece band that make it well worth hearing.
