Seattle, WA's immortal Iron Lung has bestowed upon us their fourth studio full-length, "Adapting//Crawling." This, their first album since 2013, is as fierce and uncompromising as we've come to expect from the duo of Jensen Ward and Jon Kortland, who originally bonded over a shared fascination of punishing hardcore and arcane medical barbarism. Their blasts of hardcore/agit-prop are savage and unrelenting, but Iron Lung somehow manages to imbue the negative space between blasts with an oxygen-destroying heaviness as well, perhaps the defining trademark of this group who once saw their reflection in a full-body, pressurized, metal chamber and decided to turn it into music.
