I stand by the US vs UK indie point. UK indie=MOR mainstream, boring and banal. US Indie= dreck like The Decemberists who are worse than any Coldplay or Snow Patrol.
Sorry, but this all sounds like a third-rate music journo trafficking in meaningless generalizations. You make claims about “scenes” in the US, but I can only wonder how much experience you have had *in* any of them (stateside) -- guitar & drum, dance, hip-hop, experimental/noise, or other. My impression is "none," but in any case, the distinction between a monolithic "US Indie scene" and an "underground/hipster scene" is totally meaningless, it describes no (stateside) musical reality whatsoever.I would draw a line between the US Indie scene and the "underground"/hipster scene that produces acts like Gang Gang Dance. I'll admit that its a fuzzy one, but no more so than that in the UK.
Though I must say, it's the nationalistic inflection that I find the strangest - the whole "Dude, my UK indie is better than US indie" approach . . . if there were a more boring way of talking about an already boring category of music, then I can't imagine what it would be.
