Nirvana was undoubtedly one of the most important bands of the modern era. They formed in 1987 in Aberdeen, Washington, and released their debut album in 1989, having signed to Seattle-based Sub Pop Records. The record initially only sold 30,000 copies, although it went on to sell considerably more when the band’s popularity exploded. Having been through numerous drummers and additional band members, after the release of Bleach, the group settled on the renowned trio of Kurt Cobain, Krist Novoselic and Dave Grohl. Nevermind was released in 1991, and was spearheaded by the timeless single Smells Like Teen Spirit, which almost singlehandedly brought grunge into the mainstream. Blending fierce, heavy rock 'n' roll with strong melodies, Nirvana brought a previously underground subgenre to the masses, and effectively changed pop music forever. Nevermind is regarded as a seminal rock album, and has sold in excess of 26 million copies worldwide. In the months that followed, Cobain was in the headlines for his romance and eventual marriage to Courtney Love of Hole. During the recording of their third studio album, Cobain's use of drugs began to increase. In Utero was released to wide acclaim in 1993, but in the spring of the following year, Cobain was found dead after shooting himself. The events and personal problems that led to his tragic end are still being unravelled today, and may never be fully understood. Nirvana disbanded following the death of Cobain, one of rock’s greatest icons. Fortunately, both remaining members have continued in music, with Grohl achieving huge success with Foo Fighters.
