Grunge was great, great music. Nirvana, Pearl Jam, Soundgarden, Alice In Chains, Stone Temple Pilots....the list is endless.
Do yourself another favor and see the documentary, Hype! and get the soundtrack. It tells the story of the Seattle music scene in the 80s and the early 90s that gave birth to Nirvana and tons of other great bands. The soundtrack has a ton of bands you have never heard of before and probably never would have either, and they all rock it hard!!!
