Nails are a three-piece hardcore band from California that started in 2007/2008 by Todd Jones (former member of Carry On and Terror). The band take considerable influence from 90's hardcore/grindcore, particularly Napalm Death, as well as hints of powerviolence and even doom metal. Their sound is dark, metallic, pulverizing, demolishing, crushing, chaotic, abusive, aggressive, abrasive, bludgeoning, intense, relentless, brutal, whatever adjective you want to use. This is heavy music done right. These guys are definitely one of my favourite hardcore bands to come out in recent years, so check them out.
