During the 1980's, one of the most popular and enduring genres was that of glam metal, also known as hair metal. Dominating the rock charts throughout the decade, it was getting stale. By the 1990's, this form of rock was giving way to new genres like thrash metal and alternative rock. One of the leading bands of the new alternative rock movement was a little known group from Seattle, Nirvana. Their breakthrough into the mainstream led the way to the overall popularity of alternative rock (especially grunge) during the decade, only for rock as a genre to fade out by 2000, leading the way to the popularity of pop (Hip-Hip), rhythm & blues and rap. The timeline will look at a world in which one of the most influential bands of the 1990's, didn't form, and rock still reigns supreme.
