Lou Koller, the lead singer of New York hardcore band Sick of It All, has died, prompting a tribute to his role as one of the scene’s most welcoming and influential figures. The article argues that his importance lay not only in his powerful voice and energetic performances, but in his insistence that hardcore shows should be inclusive, communal spaces where fans looked after one another.

Koller formed Sick of It All in Queens with his brother Pete in 1986, and the band became known for songs about friendship, resisting bullying and confronting racism and division. Although some called them the “Kings of New York hardcore”, Koller preferred to describe the group as its “ambassadors”, reflecting their willingness to play beyond the genre and introduce its values to wider audiences.
