Kurt Donald Cobain (February 20, 1967 – c. April 5, 1994) was an American musician. He was the lead vocalist, guitarist, primary songwriter, and a founding member of the grunge band Nirvana. Through his angsty songwriting and anti-establishment persona, he widened the thematic conventions of mainstream rock music. He was heralded as a spokesman of Generation X, and is widely recognized as one of the most influential rock musicians.
Cobain formed Nirvana with Krist Novoselic and Aaron Burckhard in 1987, establishing themselves as part of the Seattle-area music scene that later became known as grunge. Burckhard was replaced by Chad Channing before the band released their debut album Bleach (1989) on Sub Pop, after which Channing was in turn replaced by Dave Grohl. With this final lineup, the band signed with DGC and found commercial success with the single "Smells Like Teen Spirit" from their critically acclaimed second album Nevermind (1991). Cobain wrote many other hit Nirvana songs such as "Come as You Are", "Lithium", "In Bloom", "Heart-Shaped Box", "All Apologies", "About a Girl", "Aneurysm", "You Know You're Right" and "Something in the Way".
