Always a contentious genre, I'd say it's a topic ripe for discussion. Is noise music? What value does it have? What goals are trying to be achieved with noise? What separates a good noise artist from a poor one? How far does your appreciation and tolerance for noise extend? How has noise shaped the popular music landscape over time? Is there a strong emotional base in noise music, or is it purely aesthetic and visceral? Are certain types of noise music more effective than others? How should live noise performances be approached?
