Nirvana was an American rock band that was formed by singer/guitarist Kurt Cobain and bassist Krist Novoselic in Aberdeen, Washington in 1987. Nirvana went through a succession of drummers, the longest-lasting being Dave Grohl, who joined the band in 1990.
The band established itself as part of the Seattle music scene, releasing its first album Bleach for the independent record label Sub Pop in 1989. After signing to major label DGC Records, Nirvana found unexpected success with "Smells Like Teen Spirit", the band's lead single from its second album Nevermind (1991). Subsequently, Nirvana entered into the mainstream, bringing along with it a subgenre of alternative rock called grunge. As Nirvana's frontman, Kurt Cobain found himself referred to in the media as the "spokesman of a generation," with Nirvana being considered the "flagship band" of Generation X. Cobain was uncomfortable with the attention and placed his focus on the band's music, believing Nirvana's message and artistic vision to have been misinterpreted by the public. The third Nirvana studio album In Utero (1993), challenged the group's audience, featuring an abrasive, less-mainstream sound.
Nirvana's brief run ended following the death of Cobain in 1994, but the band's influence and popularity endured in the years that followed. In 2002, "You Know You're Right", an unfinished demo from the band's final recording session, topped radio playlists around the world. Since its debut, the band has sold over 25 million albums in the United States alone, and over 50 million worldwide. by en.wikipedia.org
