There were a lot of bands but I'd say for the most part different bands varied in what elements of grunge they emphasized over the others, whether it be punk, heavy metal, sludge, hard rock, industrial, etc and whether they were more rhythmic or melodic. On top of that many also developed unique tones and favorite techniques that made it possible to identify them off of that alone. In the end they maintained that core grunge sound while still differentiating themselves from each other.The problem with grunge was too many bands had the same generic sound. Didn't help much with the cross pollination of same people in different bands.
That being said I mostly liked grunge. A lot of 70's feel with a flair of 80's added to it.
Grunge roots are Seattle so everything else is kind of derivative. Big hair? I thought it died in the 80's.I think it's important to note the difference between what was considered "post-grunge" in the 90's and what was considered "post-grunge" in the 2000's. Musically, 90's post-grunge really was just grunge at heart that got the label affixed to it because it didn't trace it's roots to the the original grunge startup and adopted the sound after grunge's peak in popularity. 2000's post- grunge ("butt rock") maintained a similar song structure but sounded much cleaner and polished and typically "happier" from a lyrical standpoint, sometimes to the point of big hair style lyrics. As the 2000's went on this distinction became even greater. Bush was considered post-grunge but sounded considerably different than what would go on to become bands like Theory of a Deadman and Nickelback.
In this context I'm talking strictly lyrical content but new glam metal is actually alive and well today.Big hair? I thought it died in the 80's.
That's what I'm talking about. 90's "post-grunge" didn't have the distinct origin but still sounded just like grunge.Grunge roots are Seattle so everything else is kind of derivative.
