324

324 is a seminal fixture in the Japanese grindcore scene, formed in Tokyo in the late 1990s by veterans of the extreme metal underground. Their sound is characterized by a fusion of 'D-beat' hardcore punk and the 'HM-2' buzzsaw guitar tone typically associated with Swedish death metal.

Unlike the more 'noisecore' leaning elements of their contemporaries, 324 emphasized technical proficiency and high-fidelity aggression. Their career is marked by a series of influential splits and full-lengths, most notably 'Customized Circle' and 'Rebelgrind', which solidified their reputation for 'rebel grind' - a style that prioritizes rhythmic drive and social defiance. They are frequently cited alongside acts like Mortalized and Bathtub Shitter as part of a golden era of Japanese extreme music that exported a unique, high-intensity aesthetic to the global stage. Critical consensus highlights their ability to maintain extreme tempos without sacrificing the 'groove' essential to hardcore punk, making them a bridge between the metal and punk communities.
