Listen to stuff that was being Made concordedly with Nirvana, like Mother Love Bone. Mother Love Bone is perhaps more influential for Grunge than Nirvana. Because he killed Himself he is accorded greatness status that if you look at his music was not actually warranted. Ill give you Smells Like Teen Spirit but where else is there a really original Song that Nirvana came out with. Controversial in Rape Me but that is just the Smells Like Teen Spirit Riff Backwards. Whereas you look at songs like Riders on the Storm and other such songs from The Doors you have real influence on the music world as a Whole. Grunge was going to occur with or without Nirvana, the Psychedelic Rock that The Doors were apart with would be nothing with out The Doors and a few other bands.
I'd definately have to disagree with you STRONGLY on this statement Shadow m'boy.
I love Mother Love Bone first off. Chloe Dancer is one of the most beautiful songs I've ever heard. I used to be huge into grunge a long time ago, so I know all about that scene. MLB were hugely influential to a certain type of alternative rock music, I wouldn't necessarily say they were a grunge band. People tend to think of Grunge as any alternative rock loosely assosciated with Seattle in the early 90s and thats just not so. MLB were much more of a fusion of glam and arena rock mixed with heavier hooks. The real godfathers of grunge were a band called Green River, perhaps you heard of them? Original band for some of the guys from Mudhoney. Fantastic band, and I'd definately call them the originators of grunge over MLB any day considering MLB were only around from like 88-90 and Green River were already around by 86.
But to say Nirvana were not an influential band is just absurd my friend. If the only "original" song you can find by them is Smells like Teen Spirit (which isn't even one of their top 10 best songs) then you must not be looking hard enough. Heres a quick list of highly original and amazing songs by Nirvana besides the two hits you mentioned.
Love Buzz
About a Girl
Lithium
Come As You Are
In Bloom
Lounge Act
Something in the Way
Heart Shaped Box
All Apologies
Polly
Drain You
The Entire Unplugged Album
Look at all of that I just listed. Thats just breaking the surface. You should hear some of the solo acoustic stuff Kurt recorded before he died that they released, its fucking amazing. Nirvana were a mixture of Sabbath heaviness, punk riffs, Dark and Angry William Burroughs-style poetry and melodies worthy of the Beatles. Any and all bands playing any form of alternative rock these days could claim influence from Nirvana. Theres a reason Cobain is so glorified, and its not because he killed himself (if all you had to do was kill yourself, wouldn't there be some huge following of INXS who claim Michael Hutchene was an icon?) it's because his music was really that damn influential and amazing. It changed millions of lives.
As for the Doors and psychedelic rock, I agree to an extent, but psychedelic rock was around well before the Doors even got together. The Beatles, Moby Grape, The Byrds, and most of all the 13th Floor Elevators were tooling around with psychedlia before the Doors came together. The Doors did perfect the music though, I will agree with that. And this is coming from someone who considers Jim Morrison one of the three greatest poets of the 20th century (along with Kerouac and Ginsburg, possibly Sylvia Plath & James Joyce as well) and has heard every piece of music by him more times then I could even dare to count.
You should check out the 13th Floor Elevators, they were the first real perfect psychedlic band and nobody did it better then them except for the Doors. They had a friggin ELECTRIC JUG FOR GOD'S SAKE! Thats all you should need to know to want to go out and buy one of their albums!
Long live Roky Erickson. And being a music geek.
