Brutally hardcore at heart, Boston-area outfit Vein incorporate whatever is necessary from other genres -- including pure screamo, drum'n'bass, and late-'90s metal -- to concoct an extreme and sometimes uncomfortable blend of heaviness. After years recording demos and short sets, they made their official debut in 2018 with the Billboard-charting Errorzone. Three years later, they issued This World Is Going to Ruin You under the name Vein.Fm.
