First, define Grunge, and for that, go to Wikipedia, which says:
"The grunge movement or culture grunge movement is the media Music surrounding the grunge music genre . The grunge genre appeared as late 80's and after the drive media have accompanied artistic, literary, political ideology, and forms of exchange and social relations derived from them .
and counter anti-business stance, and the low priority grunge groups gave his image, in contrast with other previous rock moves, and several musicians of this current is characterized by his vehement rejection of theatricality and artificiality. "
However, several of the "survivors" of this move, which still remain in the mainstream of music (as Eddie Vedder, Dave Grohl or Chris Cornell) has made a radical change in his image went from grunge to cool, almost nonstop.
Many would say they "sold out", they threw all that depression constant and repeated complaints to the trash, and now are part of the system (blah, blah, blah). But this may have a reason, and if it does not, then I'm going to invent.
Grunge began as a protest, like the desperate cry of hopeless teenagers, it is true, but like anything that tries to undermine the happy "system", this ends in a way or another, engulfing and taking advantage of it, transforming it into a fashion (as happened with so many genres such as punk, late 70's). The grunge jumped from one day to the other in the suburbs of Seattle to the top of all rankings the world and around the world wore pants and shirts torn loggers.
All members of the genus, I pass just that. Ceased to be symbols of a youthful cry for help, to be rock stars. And once you get there, which is on top of "Monte pop", it is difficult to get off. Then the fashion changed, and if these stars wanted to remain in musical heaven, also had to do it. Not only the members of this movement happened in many other rock artists we see a similar change, just to name two, we can name the Red hot chili peppers or to the very Rolling Stones (except for Keith Richards, obviously .)
But because they could do this and not go away in the attempt?. Because they are not criticized too much?. On the one hand, on the important musical legacy. But on the other, and I think most important in this case, because the grunge, like all "religions" was his sacrifice, physical loss of Kurt Cobain, no doubt, most of Grunge emblem. With the death of this idol, remained perpetuated the image grunge.
Nobody on this planet will Dave Grohl discuss whether or not grunge, because he was Cobain's band mate, he was a friend of the symbol. And as with Grohl, this happens with everyone who was with Kurt, either as partners, colleagues, enemies or girlfriends. In Argentina, we can name a similar case, such as Roberto Petinatto, former High and now become one of the television hosts one of the most important channels of the country, but he was in the same band as Luca Prodan!.
Finally, we thank the " Nevermind", will continue playing like that when I edit, now or in 20 years ...
