The punk anthology I just received for Christmas includes a book with the usual critical puffery.

In it, however, is this observation: that when “punk” considered itself a “movement”, it allowed for a great range of individual styles and expressions under its umbrella; but when it began to act like a “genre” it ossified, and you end up with pop punk and Maximum RnR fanaticism.

It strikes me that it’s not the most original insight, but that doesn’t make it less valid; it also strikes me that you could comfortably insert the word “slam” in place of “punk” and not damage the truth of the statement too much.
