Split 7" releases are great when both bands are good. And luckily this time both Black Market Fetus and In Defence are good underground groups and this nasty little piece is as sweet as it is short- seven songs pass by hastily but it's certainly good enough to warrant repeated listens. Another positive is that both bands differ slightly in sound providing a little bit of variety between their respective onslaughts.
Black Market Fetus play fast-paced grind/hardcore that is heavily thrash influenced which is showcased in their use of harmonious riffing that's embedded in their usual speedy bursts of aggression. Vocalist Nate "Nightjack" Fetus alternates his vocal delivery between raspy screams and a death metal growl and if you're partial to that sort of thing then you are advised to seek out some of their other releases. There are plenty of split 7" albums to choose from.
In Defence's brand of crossover thrash/hardcore gets the winning vote on this particular release due to some good moshing breakdowns and top notch shredding along with their resemblance to The Crumbsuckers and Suicidal Tendencies.
