As the lead singer and guitarist of Nirvana, Kurt Cobain's musical success began in his twenties and was heightened when he formed the band Nirvana. Hits such as Smells Like Teen Spirit, Come as You Are," and Heart Shaped Box" helped the group achieve international success. Cobain was born in Aberdeen, WA. Hyperactive as a youngster, he was given Ritalin to help him concentrate in school and sedatives to help him sleep at night. At the age of seven, his parents got divorced. He became so difficult to live with that his parents sent him to live with relatives. This period in his life is reflected in songs such as "Sliver." With a dislike for school, Cobain spent his time painting and singing. He listened to the Beatles and the Monkees, but changed to bands such as Kiss, Black Sabbath, the Sex Pistols, and the Clash in 1979. On his 14th birthday, Cobain bought his first guitar and started experimenting with different musical styles. He also was a roadie for a Seattle group called the Melvins. He dropped out of high school a few weeks before graduation to get a job, but his efforts were unsuccessful because he couldn't hold a job for very long.
