Found this neat list at rateyourmusic: “underknown” post-rock. Of this list of 29 albums, I’ve only heard one (Cerberus Shoal’s Homb) and have only actually heard of three or four! I’ve got some exploring to do.
I found this through DJ Martian’s page — a website/blog full of links arranged in a manner that I found pretty much incomprehensible at first. It’s really best to read this thing through the RSS feeds; there are two, one for the sporadically-updated blog and one for the more regularly updated links (through del.icio.us). Once you figure out how to sift through this in an intelligible way, it’s a very nice source of regular music news.
