Nirvana

Nirvana was the leader of the rise of grunge in the nineties. Their album Nevermind sold phenomenally and helped introduce a dirty style of hard rock influenced by punk and psychedelic rock that came to define hard rock in the early to mid nineties. The original grunge bands came out of Seattle and thus were known as the "Seattle sound". The others were Soundgarden, Pearl Jam, and Alice in Chains. Nirvana was inducted their first year of eligibility, an obvious choice.
