Use Your Illusion II is the fourth studio album by the American hard rock band Guns N' Roses.
 The album was released on September 17, 1991, the same day as its counterpart album "Use Your Illusion I".
 Both of the albums were released in conjunction with the Use Your Illusion Tour.
 Bolstered by the lead single "You Could Be Mine," "Use Your Illusion II" was the slightly more popular of the two albums, selling 770,000 copies its first week and debuting at No. 1 on the U.S. charts, ahead of "Use Your Illusion I"'s first week sales of 685,000.
 As of 2010, "Use Your Illusion II" has sold 5,587,000 units in the U.S., according to Nielsen SoundScan.
 Both albums have since been certified 7× Platinum by the RIAA.
 It was also No. 1 on the UK Albums Chart for a single week.
 It is the last Guns N' Roses album to feature rhythm guitarist Izzy Stradlin.
 It also included the last Guns N' Roses song to feature drummer Steven Adler, who played on "Civil War."
The Days of Our Nights is the fifth album by American alternative rock band Luna, currently out of print in the United States.

"One in a Million" is a song by American rock band Guns N' Roses.
 It is the eighth track on the album "G N' R Lies" and was released in 1988.
 The lyrics describe Guns N' Roses singer Axl Rose's experience of getting hustled in the Greyhound bus station upon first arriving in Los Angeles.
 The song is notable not only for its controversy, but also for being one of the first Guns N' Roses songs that Axl Rose wrote solo.
 According to interviews, Rose wrote "One in a Million" on guitar (with which he was not proficient at the time), using only the bottom two strings.
 This differs from other Rose-written Guns N' Roses songs, which Rose composed on piano or keyboards.
 This is the first Guns N' Roses song to feature piano, played by Rose on the outro.
The Guns N' Roses/Metallica Stadium Tour was a co-headlining concert tour by American rock bands Guns N' Roses and Metallica during 1992.
 It took place in the middle of Guns N' Roses' "Use Your Illusion Tour," promoting their "Use Your Illusion I" & "II" albums, and between Metallica's "Wherever We May Roam Tour" and "Nowhere Else to Roam," promoting their eponymous fifth album "Metallica (The Black Album)".
 The tour's opening act was Faith No More.
 Axl Rose had wanted Seattle rock band Nirvana to be the opening act, but frontman Kurt Cobain refused.

 is the fifth studio album by the American hard rock band Guns N' Roses.

 It is also the only Guns N' Roses album not to be accompanied by a supporting tour.

 It contains the metal hits "Bang Go The Bells", "Hammer Swings Down" and "The Kid Goes Wild" which was also featured in the film "RoboCop 2".

 During his later years with Guns N' Roses, Slash formed the side project Slash's Snakepit.
 After leaving Guns N' Roses in 1996, he co-founded the supergroup Velvet Revolver, which re-established him as a mainstream performer in the mid to late 2000s.
 Slash has since released three solo albums: "Slash" (2010), featuring an array of famous guest musicians, and "Apocalyptic Love" (2012) and "World on Fire" (2014), recorded with his band, Myles Kennedy and the Conspirators.
