The term post-rock is used for quite disparate bands, though I would say they all want to move beyond the conventions of rock, but the means to get there differ from one group to another. I mean, Seefeel are basically an ambient outfit with guitars, whereas Bark Psychosis are jazzists, which happen to work within the rock idiom. Speaking of the latter, they should be seen as the Enos of the genre, i.e. they didn't establish the brand, they merely elucidated what the entire thing is all about. However, their post-rock doesn't suggest a collection of cliches about such a style in a neat package, there's a sense they're going towards the uncharted paths without any intentions. Sure, you can hear their precursors, yet they construct their own sonic identity that includes these markers.
