Short answers, pulled from the story.
Nirvana was formed in Aberdeen, Washington, in 1987, by singer and guitarist Kurt Cobain and bassist Krist Novoselic. The two met while attending Aberdeen High School and bonded over their shared connection to the Melvins' practice space.
Nirvana's first album was Bleach, released in June 1989 on the Sub Pop independent label. It achieved initial sales of 40,000 copies, driven primarily by college radio airplay, and was produced by Jack Endino with funding provided by guitarist Jason Everman.
Nevermind reached number one on the Billboard 200 in January 1992, displacing Michael Jackson's Dangerous, after the single "Smells Like Teen Spirit" received heavy MTV airplay. By Christmas 1991, the album was selling 400,000 copies a week in the US alone, and eventually sold more than 30 million copies worldwide.
Nirvana's final lineup consisted of Kurt Cobain on lead vocals and guitar, Krist Novoselic on bass, and Dave Grohl on drums. Pat Smear of the Germs joined as touring guitarist in 1993 and participated in all subsequent reunion performances.
Kurt Cobain was found dead on the 8th of April 1994, of a self-inflicted shotgun wound at his home in the Denny-Blaine neighborhood of Seattle. He had died approximately three days before his body was discovered, ending Nirvana. A public vigil on the 10th of April 1994, drew approximately 7,000 mourners at Seattle Center.
