No I may have missed your posts about Nirvana.
I think the media has more to do with the idolisation of Kurt than his looks.
I.e when they released Nevermind, Nirvana was on tour in europe, they would get phonecalls letting them know SLTS was spinning round and round on MTV.
There was no real marketing, no expensive video, MTV just decided it should play 20 times a day.
And we all know what happens to bands that get that kind of rotation on MTV.
Why Krist or Dave didn't get as much attention as Kurt is no big mystery, it happens to most bands, the front man/woman gets the most attention from the press.
And lets face it, during the Nirvana years, Dave wasn't exactly the most vocal person.
When something hits, and hits big, all record labels (the major ones) wants to find the new similar act and make as much money, this happens to all different waves of music.
Ofcourse the bands can choose if they want to jump on the wagon or not.
Alice in Chains, Pearl Jam got on that wagon, they could have chosen to stay low key.
But also the music has a lot to do with it, I mean Melvins also jumped on that wagon to a certain degree when signing with Atlantic but their music is not as easy to sing along with at a first glance.
When Nirvana got big I think they were put in an odd position, I mean while they wanted to sell records, they didn't want to do tv shows (they would toss around their instruments on live broadcasts if made doing a playback show, or they would play a totally different song than what was agreed beforehand with the producers), so they tried to keep their "punk stamp" and still sell records, it's a difficult game.
I still think he was a down to earth guy compared to most people that have sold that many records and given that kind of media attention.
