Yeah, but theres always new movements.
And I must say, prog is doing a lot better than punk right now, we have a lot of hot bands coming out of the woodwork that are prog (TMV, Battles, Muse, Oceansize, Kayo Dot, Coheed & Cambria, Fall of Troy, Mew, Secret Machines) while no punk band has been relevant since the 90s.
So yeah, thats great irony considering some people never seem to shut up about how "punk killed prog"
Which was never true, prog collapsed under its own weight and overexposure, punk just further pushed it into obscurity. But now that we have a lot of these bands bringing the genre back on its feet and making it relevant again, well I think its great.
