That's cool, man... it's a great genre.
I just watched last night Mono's DVD The Sky Remains The Same As Ever, since I've also seen Sigur Ros's DVD, and it seems the trend with post rock DVD's is to not have a conventional concert or whatever. Sigur Ros document there tour back home and the sights and so on , and Mono have thjis artistic music filled documentary (I don't really know how to explain it). On the whole, it's cool that they're trying new things, but sometimes you just feel like watching a live show at home, and not in the mood for more than that. But Mono's DVD is really great, way better than Sigur Ros's (of which I didn't watch the whole thing). Also, it was cool seeing the guys from Explosions In The Sky hanging out with them.
Finally, I just wanted to post this since, even though it isn't the whole song, I find it fucking awesome:
