i reckon this might be pretty fruitless, but it needs finding.
A GOOD number of months ago, there was a thread that had loads o' links to massive post rock type stuff. Someone gave up a youtube vid of something (possibly Explosions In The Sky) that had a face-melting distorted guitar line dominating the opening of the tune. Im talking big drums behind a Deftones-esque crunch. The vid might have had a cloudscape in it??
So there it is. I've vaguely described what could possibly be hundreds of post-rock tunes. But that's all i've got. Help if you can, as i'm aching to here it again.
