Yeah, if you say 'post-rock' most people will think GY!BE first. So, in that regard, i guess they would be THE post-rock to check out. They just don't excite me in the same way Explosions, Mogwai and 65DOS do.
If you haven't herad 65daysofstatic, you're basically missing out. They are totally, like, my favourite band evah. Epic post-rock with a glitchy electronica twist. I'll PM you a tune or two.
Anyway, yeah. GY!BE, eh? Good stuff.
