Harpoon

Harpoon is a significant entity within the Chicago extreme metal underground, notable for its 'supergroup' status featuring members from 7000 Dying Rats, Lair of the Minotaur, and Weekend Nachos. Their sound identity is a volatile mix of thrash metal's riff-heavy structure and grindcore's uncompromising speed and brevity.

This hybridity places them in a lineage of Midwestern extreme music that favors grit and raw emotional output over technical polish. The band's association with engineer Sanford Parker and mastering legend Scott Hull (Pig Destroyer) is central to their sonic signature, ensuring a high-pressure, dense audio profile. Culturally, they represent the bridge between the 90s Argentinian thrash scene (via their early work like 'Batalla Eterna') and the later 2000s American sludge/grind movement. Critical consensus highlights their ability to maintain a sense of groove even at extreme tempos, making them a staple for fans of the Interloper and Relapse Records rosters.
