No Brain (Korean: 노브레인; Hanja: 怒브레인; lit. 'Angry Brain') is a South Korean punk rock band widely considered one of the godfathers of the Korean punk scene. Originally part of Korea's homegrown underground punk movement, known as Chosun Punk, in recent years the group has enjoyed mainstream success both with their music and their emerging acting and hosting careers. Their name comes from their desire for concert-goers to leave their rational minds at the venue doors.
