Strange, you are the second person who told me that. I came in right as that era was fading. It felt like the last time we had real offline vibes and local scenes.
Grunge rock was peak music. This is factual and true.
I recently noticed that lots of young people seem to be into music from the 90s and early 2000s. Was never that into grunge myself but there are a few Pearl Jam and Nirvana songs I like.
