Having previously released material mastered by Dennis Pleckham of Bongripper and taken musical cues from Sunn O))), Chicago’s Plague of Carcosa are no strangers to a heavy riff. Their 2018 release ‘Rats In The Walls’ required no more than just one track to make its point, but since that number was often delivered at a crawling speed and dragged out to almost fifteen minutes, the effect was like experiencing a full four song EP from most doom/sludge bands.
