Nirvana was an American rock band formed in Aberdeen, Washington, in 1987. Consisting of lead vocalist and guitarist Kurt Cobain and bassist Krist Novoselic, the band became a defining act in the grunge movement of the early 1990s, with drummer Dave Grohl joining in 1990. Nirvana's dissonant sound and Cobain's introspective lyrics on albums such as "Nevermind" (1991) and "In Utero" (1993) resonated with a disaffected youth culture, and their hit "Smells Like Teen Spirit" is often hailed as an anthem of Generation X. Their influence endures in the rock music genre, despite Cobain's untimely death in 1994.
