Justin Drew Bieber

Justin Drew Bieber (pronounced /ˈbiːbɚ/ bee-bər, born March 1, 1994).is a Canadian pop/R&B singer-songwriter and actor. Bieber was discovered in 2008 by Scooter Braun, who happened to come across Bieber's videos on YouTube and later became his manager. Braun arranged for him to meet with Usher in Atlanta, Georgia, and Bieber was soon signed to Raymond Braun Media Group (RBMG), a joint venture between Braun and Usher and then to a recording contract with Island Records offered by L.A. Reid. His debut single, "One Time", released worldwide in 2009, peaked in the top ten in Canada and charted in the top thirty in several international markets. His debut release, My World, followed on November 17, 2009, and was eventually certified platinum in the United States. He became the first artist to have seven songs from a debut album chart on the Billboard Hot 100.

Bieber's first full studio release, My World 2.0, was released on March 23, 2010 and has since received similar success; it debuted at number one and within the top ten of several countries, and was certified platinum in the United States. It was preceded by the worldwide top-ten single, "Baby", in January 2010. The music video of "Baby" is currently ranked as the most viewed and most discussed YouTube video, and was the most disliked until being overtaken by Rebecca Black's song Friday. Bieber followed-up the release of his debut album with his first headlining tour, the My World Tour, the remix albums My Worlds Acoustic and Never Say Never – The Remixes, and the 3D biopic-concert film Justin Bieber: Never Say Never – which had an opening weekend gross that nearly matched the record for the biggest opening weekend for a concert-film.

Bieber has been nominated and awarded numerous accolades over the past few years, winning Artist of the Year at the 2010 American Music Awards, and being nominated for Best New Artist and Best Pop Vocal Album at the 53rd Grammy Awards, among others. Bieber is considered a teen idol, and has been subject to acclaim from fans, as well as criticism and controversy from matters concerning his popularity and image...

Nirvana Band Rock and Roll American

Nirvana was an American rock band that was formed by singer/guitarist Kurt Cobain and bassist Krist Novoselic in Aberdeen, Washington in 1987. Nirvana went through a succession of drummers, the longest-lasting being Dave Grohl, who joined the band in 1990.

The band established itself as part of the Seattle music scene, releasing its first album Bleach for the independent record label Sub Pop in 1989. After signing to major label DGC Records, Nirvana found unexpected success with "Smells Like Teen Spirit", the band's lead single from its second album Nevermind (1991). Subsequently, Nirvana entered into the mainstream, bringing along with it a subgenre of alternative rock called grunge. As Nirvana's frontman, Kurt Cobain found himself referred to in the media as the "spokesman of a generation," with Nirvana being considered the "flagship band" of Generation X.[1] Cobain was uncomfortable with the attention and placed his focus on the band's music, believing the band's message and artistic vision to have been misinterpreted by the public, challenging the band's audience with its third studio album In Utero (1993).

Nirvana's brief run ended following the death of Cobain in 1994, but the band's influence and popularity endured in the years that followed. In 2002, "You Know You're Right", an unfinished demo from the band's final recording session, topped radio playlists around the world. Since its debut, the band has sold over 25 million albums in the United States alone, and over 50 million worldwide.
