On the Botch comparison: The (International) Noise Conspiracy is catchy though inferior, but has anyone heard Text? It's Jon Brännström and David Sandström's new(ish) band, it has one album, and it's brain-damagingly good. They do dub, musique concret, a capella hardcore requiems, etc etc.
And The Shape of Punk to Come was like, maybe the best album ever. I wish more punk and hardcore bands would push themselves creatively like that.
