Nirvana was a popular American grunge rock band founded in 1987 in Aberdeen, Washington. With the lead single "Smells Like Teen Spirit" from the band's 1991 album Nevermind, Nirvana exploded into the mainstream, bringing along with it an offshoot of punk and alternative rock that the mainstream media of the time referred to as grunge. Other Seattle grunge bands such as Alice in Chains, Pearl Jam, and Soundgarden also gained in popularity, and, as a result, alternative rock became a dominant genre on radio and music television during the early-to-middle 90s.
As Nirvana's frontman, Kurt Cobain found himself referred to in the media as the "spokesman of a generation", with Nirvana the "flagship band" of "Generation X". Cobain declined the position, and placed his focus on the band's music, challenging the band's audience with their third album In Utero. While Nirvana's mainstream popularity waned in the months following its release, their core audience cherished the band's dark interior, particularly after the band's 1993 performance on MTV Unplugged.
Nirvana's brief run ended with the death of Cobain in 1994, but the band's popularity expanded in the years that followed. Eight years after Cobain's death, an unfinished demo that the band recorded two months prior to Cobain's death topped radio play lists around the world. Since their debut, the band has sold more than fifty million albums worldwide (see also Best selling music artists), including more than ten million copies of Nevermind in the US alone. Nirvana remains a consistent presence on radio stations worldwide. Courtesy of wikepedia
