Extremity has been Anaal Nathrakh's stock in trade for more than two decades. 20078's Hell Is Empty, and All the Devils Are Here is the fourth full length album by the British extreme metal duo. Napalm Death's Shane Embury, an ally of the core duo for several years at this point, plays bass on a few tracks, but the primary instrumental contributions are by Mick Kenny, while Dave Hunt performs the vocals, assisted here and there by guests (Circle of Dead Children's Joe Horvath and Exploder's Dirty Von Donovan). This is a more precise, death metal and grindcore-inspired version of Anaal Nathrakh.
