Nirvana was an American rock band formed in 1987. It was founded by lead singer and guitarist Kurt Cobain and bassist Krist Novoselic. Though the band dissolved in 1994 after the death of Cobain, their music maintains a popular following and continues to influence modern rock and roll culture. Nirvana found unexpected mainstream success with "Smells Like Teen Spirit", the first single from their landmark second album Nevermind (1991). Nirvana's sudden success popularized alternative rock, and Cobain found himself described as the "spokesman of a generation" and Nirvana the "flagship band" of Generation X. During their three years as a mainstream act, Nirvana was awarded an American Music Award, Brit Award, Grammy Award, seven MTV Video Music Awards and two NME Awards. They have sold over 25 million records in the United States and over 75 million records worldwide, making them one of the best-selling bands of all time.
