Sorry for starting the topic then running off - I'm on west coast time, you know?
I too thought Mudhoney would be the first to make it big. But, the lack of a catchy video did them in.
I too think that Nirvana gets credit for revolutionizing music by being at the right time and the right place, not by being the best at what they did. They are far better then the copiers already mentioned (Candlebox, Bush, STP, etc. though I am guilty of seeing all of them live at some point).
I heard Nirvana on Sunday night LA radio long before I saw them on MTV, but the instant I saw the video, I knew things were going to change. We live in a picture driven world now.
The industry was devoid of anything with substance at the time and had completely burned out on the hair bands. If I remember correctly, the hair bands were making hits with their one acoustic track, and folks were buying the albums because of that track and were ignoring the rest of the crap. If I could have a dollar for everytime I've gone through somebody's collection and found Extreme: Pornographity in their collection and asked them to name two songs off of it and they couldn't. And those that could would say "Cold Hearted" with "More than Words" and not a single person could ever answer a third song.
The modern rock stations that had survived on the new wave eighties were on the brink of BQing. I remember turning off KROQ somewhere around 1986/7 when that song "I wanna be a Cowboy, and you can be my cowgirl" by Boy's Don't Cry Cry and thinking this is the end of radio as I know it. Metal bands were in, new wave was out and I was listening to classic rock.
Nirvana put a picture to the movement, a brilliant picture at that, and no matter what you envision is being rebelled against in that video, you put it with something. I put it with the music industry.
So while I agree that no matter what the Pumpkins could have done, despite being far superior musically, they didn't have the timing or the pictures that the media wanted to put to the movement and will never be held in the same accolades, even had Cobain not killed himself and Billy did. So I agree that MTV2 runs the Pumpkins 10 Year Anniversary and not MTV.
