In what US state was the rock band Nirvana founded?

Nirvana was an American rock band formed in Aberdeen, Washington, in 1987. Founded by lead singer-songwriter and guitarist Kurt Cobain (February 20, 1967 – April 5, 1994) and bassist Krist Novoselic (born May 16, 1965), the band went through a succession of drummers before recruiting Dave Grohl (born January 14, 1969) in 1990. Nirvana's success popularized alternative rock, and they were often referenced as the figurehead band of Generation X. Their music maintains a popular following and continues to influence modern rock and roll culture.

In the late 1980s, Nirvana established itself as part of the Seattle grunge scene, releasing its first album, 'Bleach', for the independent record label Sub Pop in 1989. They developed a sound that relied on dynamic contrasts, often between quiet verses and loud, heavy choruses. After signing to major label DGC Records in 1991, Nirvana found unexpected mainstream success with 'Smells Like Teen Spirit', the first single from their landmark second album 'Nevermind' (1991). A cultural phenomenon of the 1990s, the album went on to be certified Diamond by the RIAA. (Recording Industry Association of America).

Nirvana disbanded following Cobain's suicide in April 1994. Various posthumous releases have been overseen by Novoselic, Grohl, and Cobain's widow Courtney Love. The posthumous live album 'MTV Unplugged in New York' (1994) won Best Alternative Music Performance at the 1996 Grammy Awards.
