Nirvana was an American rock band formed by singer and guitarist Kurt Cobain in 1987. Nirvana went through a succession of drummers, the longest-lasting being Dave Grohl, who joined in 1990 and is today the front man of Foo Fighters.
Despite releasing only three full-length studio albums in their seven-year career, Nirvana has come to be regarded as one of the most influential and important alternative bands in history.
Though the band dissolved in 1994 after the suicide of Cobain, 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 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.
Nirvana found unexpected success with Smells Like Teen Spirit, the first single from the band's second album Nevermind in 1991.
Nirvana's career ended following the death of Cobain in 1994, but various posthumous releases have been issued since, overseen by Dave Grohl, and Cobain's widow Courtney Love.
Since its debut, the band has sold over 5 million records worldwide, making them one of the best-selling bands of all time.
And they played in Leeds!
