Okay, as many of you MAY now, I am a HUGE grunge fan. From NIRVANA and Alice in Chains to Mudhoney and the Melvins, it's all great. Unfortunately, grunge is constantly being mocked and/or misunderstood, and I thougt I might as well clear some stuff up for people who may not already know.
Grunge is a mixture of alternative rock, metal, and punk/hardcore punk.
Nevermind by NIRVANA, Ten by Pearl Jam, Superunknown by Soundgarden, Core by STP, Above by Mad Season, Apple and Shine (and anything else) by Mother Love Bone, and the like ARE NOT GRUNGE RECORDS!!! MOST ARE CORPORATE ALTERNATIVE ROCK RECORDS!!! OTHERS ARE OVER-PRODUCED HARD ROCK RECORDS, ET CETERA!!!!!
If Nevermind and Ten defined grunge, I wouldn't like it.
In Utero by NIRVANA, Vitalogy by Pearl Jam, anything by Alice in Chains (although it's closer to just plain metal),Rubberneck by the Toadies, Superfuzz Bigmuff by Mudhoney, Gluey Porch Treatments by The Melvins (although more metal, usually), the like ARE GRUNGE RECORDS!!!!!
Now, moving on to more recently, just because a genre has grunge in it doesn't mean it IS grunge. That's right people, I'm talking about post-grunge, that poppy alternative/hard rock we all hate. Okay, so the bands labeled as such listened to Nevermind, DOESN'T MEAN THEY'RE GRUNGE. Post-grunge is the red-headed step-child of grunge that was never meant to be, and never should have been. Nickelback and Staind and Godsmack and Everclear and others are all CORPORATE ROCK BANDS. That's not grunge.
Anyway, I could go on some more, but then i'd just ramble. That's the basics. Please, if not understood already, understand your early 90s alternative rock, my friend.
