Pearl Jam were great, more than any other band at the time they symbolised the whole Seattle vibe and the type of kids who couldn’t identify with spandex and make-up and just wanted to get back to a more down-to-earth sound and play music. Just like Punk, Grunge became a whole genre that affected everything from fashion to films. These genres never really last because the record companies get onto it and all their A&R people change overnight from wearing tight jeans and big hair to long shorts and lumberjack shirts. They are fickle mother fuckers and once they find the next big thing there is blood in the water and a whole lot of bands who are not very good jump in. The beauty of it is that the really good bands go on to become timeless classics.
