The Dead Neanderthals is composed of two members, Otto Kokke on saxophone and Rene Aqarius on drums. After first collaborating online, they began improvising live, and have released several albums. The Quietus described their 2012 album Jazzhammer/Stormannsgalskap as a mighty "pounding headache of rampaging blastbeats, distorted foghorn drones and radioactive seagull squalls." Their fourth album, Polaris, was in contrast completely acoustic.
According to The Quietus, "Whether forcing the twitching viscera of free jazz through a grindcore blender, slicing the eyeball of European improvisation with a metal blade, or eviscerating the whole lot in a maelstrom of noise, the sax-drums duo of Otto Kokke and Rene Aquarius pay little heed to the boundaries of genre.
