Yep, imagine taking your young daughter to see Sigur Ros aged 10 or whatever she was, she's 28 this month and still listening to them
The whole rebelling against the parents was more relevant in the teds to -punks era but post-punk, I don't think that happens anymore
Because from that era onwards, parents stopping telling their kids to turn that rubbish off and listened to it themselves more because they grew up rebelling themselves and understood the situation more, the musical parent/kid interface totally changed, and there was nothing to rebel against (generalizing of course)
It went from turn that rubbish off to, that's cool who is it?
This also coincides with the end of the youth cult phenomenon
