Nirvana
A wonderful band comprised of Kurt Cobain, Krist Novoselic, and Dave Grohl. Had a large number of hits and great album sales until 1994, when Kurt commited suicide (or was murdered, as is some people's opinion that I do not share).
Contrary to popular belief, Nirvana was not the first grunge band. The band that created grunge was Mudhoney, like 'em or not.
