Nirvana is an American rock band formed by vocalist and guitarist Kurt Cobain and bassist Krist Novoselic in Aberdeen, Washington, in 1987. Several drummers changed in the lineup; drummer Dave Grohl played with the band the longest. Nirvana gained unexpected success with the song "Smells Like Teen Spirit" from their second album Nevermind, released in 1991. Nirvana subsequently entered the music mainstream, popularizing a sub-genre of alternative rock called grunge. Kurt Cobain became in the eyes of the media not just a musician, but "the voice of a generation", and Nirvana became the flagship of "Generation X". The short but bright history of the band was interrupted by Kurt Cobain's death on April 5, 1994, but in the following years the team's fame only grew.
