Radric Davis (born February 2, 1980), better known by his stage name Gucci Mane, is an American rapper. He debuted in 2005 with Trap House and followed with albums such as Hard to Kill in 2006, Trap-A-Thon and Back to the Trap House in 2007. In 2009, his second studio album The State vs. Radric Davis was released, and The Appeal: Georgia's Most Wanted was released in 2010, and is his highest charting album so far. Gucci Mane has released many other mixtapes and independent albums as well.

While serving a six-month jail term for assault in late 2005, Davis was charged with murder, though the charges were later dropped due to a lack of evidence. In 2009, he served a year-long county jail sentence for violating probation for his 2005 aggravated assault conviction.

Davis was born in Birmingham, Alabama, and later moved with his single mother to Atlanta. He enjoyed writing poetry as a child, and began rapping at age 14.

In 2005, Davis released his independent debut album entitled Trap House, which featured the successful single "Icy" with Young Jeezy. Disputes over the rights to this single caused a rift between the two artists. Hard to Kill followed in 2006. Hard To Kill included the hit single "Freaky Gurl". The song peaked at number 12 on the Hot Rap Tracks, number 19 on the Hot R&B/Hip-Hop Songs, and at number 62 on the Hot 100.

Kurt Donald Cobain (February 20, 1967 – April 5, 1994) was an American singer-songwriter, musician and artist, best known as the lead singer and guitarist of the grunge band Nirvana. Cobain formed Nirvana with Krist Novoselic in Aberdeen, Washington in 1985 and established it as part of the Seattle music scene, having its debut album Bleach released on the independent record label Sub Pop in 1989.

After signing with major label DGC Records, the band found breakthrough success with "Smells Like Teen Spirit" from its second album Nevermind (1991). Following the success of Nevermind, Nirvana was labeled "the flagship band" of Generation X, and Cobain hailed as "the spokesman of a generation". Cobain, however, was often uncomfortable and frustrated, believing his message and artistic vision to have been misinterpreted by the public, with his personal issues often subject to media attention. He challenged Nirvana's audience with its final studio album In Utero (1993).

During the last years of his life, Cobain struggled with heroin addiction, illness and depression. He also had difficulty coping with his fame and public image, and the professional and lifelong personal pressures surrounding himself and his wife, musician Courtney Love. On April 8, 1994, Cobain was found dead at his home in Seattle, the victim of what was officially ruled a suicide by a self-inflicted shotgun wound to the head. The circumstances of his death at age 27 have become a topic of public fascination and debate. Since their debut, Nirvana, with Cobain as a songwriter, has sold over 25 million albums in the U.S. alone, and over 50 million worldwide.
