Personally, most of the post-rock I listen to I like because it's NOT really "experimental" but more based on what classically sounds good - GY!BE, Labradford, Mono, Mogwai, bands like that. I don't think most people think such music is necessarily breaking new ground in terms of structure, mood, chord progressions or whatever.
Yay, I'm pleased to hear that. My beef is just that there are these new bands which I think are real, dyed in the wool, card-carrying Post-Rock Bands. They sound like they've heard post-rock stuff, that they have a clear picture of what post-rock is, and they want to do the same. Wait, that's not my beef.
My beef is that fans of these bands seem to consider them more adventurous or more "out there" (dare I say, avant-garde) than other bands working to find their niche within a clean-cut genre, be it psy-trance or baile funk or garage rock.
I admit, I also really don't understand the deal with Sigur Ros being post-rock, and it is something of a bug-bear for me. I bought their first EP when it came out, just because it was on Fat Cat and up until that point I'd been following that label pretty religiously, but, man, it sounded tired. I'd heard things that were really similar before, even on quite improbable things like The Verve's early EPs and first album (back when they were Verve). No one would EVER call the Verve post-rock, right? But mostly I'm thinking about shoegazer stuff... Fat Cat had already released things by Transient Waves, which were sorta on some post-My Bloody Valentine kick, and I just thought "oh, more modern shoegaze, with some more Lanois / Eno shit going on ... no wonder these guys are massive rockstars in their home country". I sold it on pretty swiftly. Then suddenly this band which I thought sounded incredibly like a whole lot of late 80s / early 90s music suddenly got heralded as the flag-bearers of a genre which, when it was initially invented, described something quite different. I was a bit - how do you say? - "WTF dudes" about it.
That said, I don't see how one could listen to, say, Hash Jar Tempo or Flying Saucer Attack and NOT think that those kind of "post-rock" bands are doing something original (whether you like it or not).
Never heard Hash Jar Tempo. Fucking funny name...
Must be a pun on Ash Ra Tempel, right? Just did a google, if it involves Roy Montgomery it's probably pretty good. Another guy who's been churning out psychedelic waves of good times since before "post-rock" was coined.
I used to listen to Flying Saucer Attack a lot when I was at school, but again, this is an old band who used to be considered among bods I talked to IRL and on the internet as part of the shoegaze and blisspop school of things... fitting into that noisy, soaring 90s UK indie thing you might want to rope bands like Swervedriver or Ride or whoever else into. They've been retro-actively brought under the post-rock umbrella (like Labradford above and, most confusingly, Slint upthread), presumably exactly because they sound original... I think they're great, but I got quite sick of them. I wish I hadn't been so ruthless in selling off CDs.
So those examples are not what I was digging at (not that I made it clear in my other post - I'm not giving you shit).
