Bridging the divide between old-school filth and new-school polish is a hard trick to pull off for any forward-thinking metal band, but Copenhagen’s Cabal seem to have nailed it first time out. With a sound that blends Meshuggah's polyrhythmic attack with the sledge-hammer downtempo deathcore of The Acacia Strain, debut album Mark Of Rot ticks plenty of contemporary boxes, but it’s also really, really fucking creepy and grim. Formed in 2015 by guitarist and noted producer Chris Kreutzfeldt, Cabal are turning deathcore black.
