Doom ‘n’ roll juggernaut ILSA have more than proven their devotion to woofer-quaking riffage with previous outings on A389 Recordings, but now the quintet has made the move to Relapse for their forthcoming Corpse Fortress LP, due on March 2nd. The Baltimore/D.C. band’s latest circus sideshow of discordant hate-riffs and screams from the void is “Hikikomori,” the group’s lead single from Corpse Fortress and out today. Titled after a Japanese term for reclusive and antisocial individuals, the track is propelled by a singular sludgy riff straight out of the Buzzov*en book of misanthropy, broken out by a particularly amazing dual-lead section towards the second chorus that will send a chill up your spine. Check the song out above; you can pre-order the album via Relapse.
