For a number of reasons, I’ve been pretty erratic in keeping up with rec.music.progressive in the past few months. The signal-to-noise ratio seems to be getting constantly worse, and whenever I scan the threads I usually only find a few things of interest. The forum I read most often these days is ProgressiveEars, which in the past couple years has exploded in membership and activity. The forum there has a lot of good discussion about actual music, threads about specific bands, and so on; stuff that rmp hasn’t had in volume for a while, it seems.
That said, I’m finding this current thread about Pink Floyd absolutely hilarious.
