good points,,,i think with pearl jam or anyone of them ,if they were the 'seattle'sound or from there it was a given it was grunge era,vedder wasn't from there I believe he kinda fell into pearl jam,stone temple pilots came out and they were far from grunge as well but they were played or lumped in there as well.
Yeah alot of the so called grunge sound was a product of a shift is sound recording techniques.
Higher compression, allowed for more distortion on an albums tracks, which in turn meant that the tempo had to be slowed down. The singer voice also changed as the ability to sing live became secondary, which is where the dominance of throat singers came from.
This also allowed for better sound production on music videos which were still the corp of everything.
But this started before the 90s, gnr for example showed the beginnings of a new type of music that was tv speaker friendly.
Which is why people completely forget that this revolutionary sound wasnt really a product of the bands.
The reason the 80s 90s turnaround was so drastic, is the 80s was all about a thinner musical sound, as it was the best they could do to make it on mtv.
The grunge sound really was just a rehash of black sabbath type blues metal, and punk rock. The social aesthetic and the sound production technology is what made it so big.
