Testosterone hangs in the air with such clammy fetor you taste it on your lips. America teetering on the edge of war with Iran over desperate displays of military virility, a victim of gang rape is convicted of ‘causing public mischief’ as the alleged attackers sing ”the Brit is a whore” after being released without charge, and the grim figures of femicide continue to climb in cartel-ravaged Mexico. The more masculinity is dissected and scrutinised whether through art, academia or activism, the greater the ferocity of the agents of patriarchy are in violently silencing any such discourse, and the world is more dangerous for it.

Building a reputation as the Bristolian vanguard of cutting edge underground music, sonic agitators Avon Terror Corps (an amalgamation of musical misfits including Schwet, Bokeh Versions, Bad Tracking among a host of others) have extended their slimy tentacles beyond the South West with new label subsidiary Global Terror Corps in a mission to deliver uncompromising, genre-defying acts from the dankest corners of planet Earth. The first release under this moniker is EP I’m Not What I Was by Aussie/German trio Concentration, a visceral powerhouse act of industrial smut comprised of artists Zachariah Kupferminc, Matt Sativa and Thrush twisting heads clean off with their live sets of hellish volatility.

The scraping electro-punk as heard on prior album Premature still grinds unmercifully but with greater ephemeral potency across four tracks of distilled fury. EP opener ‘Circumcision’ is a squealing vomit of naked, runtish neuroticism impotently wailing against the rabbi’s knife amid crushing pummeling drums coming close to the power electronics of Whitehouse were it not for the steady hypnotic tempo of the percussion. The stream of consciousness lyrics revealing the layers of pent-up, Jewish dysmorphia take terrifying turns, sexual humiliation congeals to trans-generational Holocaust trauma with tortured confusion, yet Zupferminc’s nasal whine, references to “fucking Guardian articles” and skewed klezmer pieces trigger a nervous hilarity to the nightmare.

Stuttering glitchy beats palpitate on ‘Jihadi Dole Bludger’, a cavernous momentum drives the track around points of eerie, terse quiet and warped vocals, before the synth heavy ‘Spiderfuck’ pierces with Wax Trax! throb, arpeggios and drum machines creating a subtle groove beneath the noxious miasma. Last track ‘Dead Men Don’t Rape’ honours the scathing defiance against male entitlement and sludgy-grunge delivery of 7 Year Bitch’s original but adds further layers of haunted discord and collages of reverb drenched suffering.

The testosterone that clung stubbornly on your lips is replaced with blood, pre-cum, and testicular viscera. I’m Not What I Was is a horribly fascinating, putrid dry-retch of disgust against poisonous machismo, as powerful as a sledgehammer to your face but revealing the deeply insecure and fearful heart of toxic masculinity with surgical precision.
