But even cranked up into the overdriven red, none of the aforementioned bands would sound even remotely heavy placed next to New York no-wave icons Swans’ seminal 1984 album Cop. Musically pulverising and emotionally gruelling to an insane degree, it conjures a near-chewable atmosphere of tension, terror and torment. Similarly, if you have the stomach for heaviness in its most avant-garde and hostile form, listen to Japanese noise artist Merzbow’s 1994 masterpiece Venereology on headphones at high volume and try to string a sentence together afterwards.
