Lou Koller was a true friend, a father, a brother, a groundbreaking creative force in the punk, metal, and hardcore scenes, and a frontman like no other. We're going to miss him dearly. Rest easy, Lou. Our hearts go out to the Koller family and our brothers in Sick of It All. pic.twitter.com/UtagYBJsvs
