Puritanism and noise do work well together, making a political point with well-executed noise behind it can be very intense, especially when you agree with the point being made (as i do with straight edge, even though i dont live up to my own standards on that point). But the reason ive been posting here recently was because i heard Grunt's latest album, World Draped In a Camouflage. That album is not explicit, I dont know the true opinions of the artist, and i dont know what point (if any) he is trying to make (yes i know its his website).
For me, straight down the line PE is best when it has a clear, stated opinion to force home (whether i like that opinion or not). So i like the idea of straight edge noise. Especially that track with the sampled druggies voices. Very effective.
