Crosby, Stills & Nash (CSN) was a vocal folk rock supergroup made up of American singer-songwriters David Crosby and Stephen Stills and English singer-songwriter Graham Nash.
 They were known as Crosby, Stills, Nash & Young (CSNY) when joined by Canadian singer-songwriter Neil Young, who was an occasional fourth member.
 They were noted for their intricate vocal harmonies, often tumultuous interpersonal relationships, political activism, and lasting influence on US music and culture.
 Crosby, Stills & Nash were inducted into the Rock and Roll Hall of Fame and all three members were also inducted for their work in other groups (Crosby for the Byrds, Stills for Buffalo Springfield and Nash for the Hollies).
 Neil Young has also been inducted as a solo artist and as a member of Buffalo Springfield.
Buffalo Springfield is a compilation album released on Atco Records in 1973.
 It is the fifth album by rock band Buffalo Springfield, and their second compilation.
 It was assembled by the label well after the band had broken up at a time when Crosby, Stills, Nash & Young were both quite popular and had not released any new material as a group for over two years, with their 1974 reunion tour eight months away.
 It features a nine-minute extended version of the song "Bluebird" by Stephen Stills (consisting of a live jam appended to the studio version), only available elsewhere on the Warner Special Products LP compilation "Heavy Metal – 24 Electrifying Performances" (Volume 2 in the "Superstars of the 70's" series), released in 1974.
 It has never been issued on compact disc in North America and is currently out of print.

Buffalo Springfield is a career retrospective album by the 1960s folk rock band of the same name, released in 2001.
 Band member Neil Young assembled the tracks in chronological order to show how the band evolved and disintegrated in the span of two years.
 Of the four CDs, the first three represent the actual box set while the fourth CD contains the band's first two albums, all but two tracks of which had already appeared in identical versions elsewhere on the first three CDs.
 It reached #194 on Billboard's Top 200 Album chart, and stayed on the chart for the single week.
 The set omits the stereo version of the "Buffalo Springfield" album, the mono version of "Buffalo Springfield Again", the album versions of "On The Way Home", "Pretty Girl Why", and "Four Days Gone" from "Last Time Around", and the songs "Carefree Country Day" and "In The Hour Of Not Quite Rain" from "Last Time Around".
 It also lacks the long version of "Bluebird", only ever issued on the band's self-titled 2-LP compilation, "Buffalo Springfield," released in 1973.
Neil Percival Young, {'1': ", '2': ", '3': ", '4': "} (born November 12, 1945), is a Canadian singer-songwriter, musician, producer, director and screenwriter.
 After embarking on a music career in the 1960s, he moved to Los Angeles, where he formed Buffalo Springfield with Stephen Stills, Richie Furay and others.
 Young had released two solo albums by the time he joined Crosby, Stills & Nash in 1969, in addition to two as a member of Buffalo Springfield.
 From his early solo albums and those with his backing band Crazy Horse, Young has recorded a steady stream of studio and live albums, sometimes warring with his recording company along the way.
Long May You Run is an album credited to the Stills-Young Band, a collaboration between Stephen Stills and Neil Young, released in 1976 on Reprise Records, catalogue MS 2253.
 It peaked at #26 on the "Billboard" 200 and certified gold in the U.S. by the RIAA.
 The album is the sole studio release by Stills and Young in tandem.
 Musically, it follows mostly in a similar vein to the duo's other joint work with Buffalo Springfield and Crosby, Stills, Nash & Young, traversing various facets of Americana and folk music, while songs such as "Make Love To You" have something of a jazz feel, and the extensive use of synthesised strings on the second side give the songs an art rock sound.
"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.
Steven Adler (born Michael Coletti; January 22, 1965) is an American musician.
 He is best known as the former drummer and co-songwriter of the hard rock band Guns N' Roses, with whom he achieved worldwide success in the late 1980s.
 Adler was fired from Guns N' Roses over his heroin addiction in 1990, following which he reformed his old band Road Crew and briefly joined BulletBoys, which both proved unsuccessful.
 During the 2000s, Adler was the drummer of the band Adler's Appetite, and from 2012, he had held the same position in the band Adler.
 In early 2017, Steven Adler declared that he has no intention to continue with the band, and that the band has now dissolved, and the reason is his lack of interest in performing during poorly attended concerts.
 He appeared on the second and fifth seasons of the reality TV show "Celebrity Rehab with Dr. Drew", as well as on the first season of its spin-off "Sober House".
 He was inducted into the Rock and Roll Hall of Fame in 2012 as a member of Guns N' Roses.
Saul Hudson (born July 23, 1965), better known by his stage name Slash, is a British-American musician and songwriter.
 He is best known as the lead guitarist of the American hard rock band Guns N' Roses, with whom he achieved worldwide success in the late 1980s and early 1990s.
 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.
 He returned to Guns N' Roses in 2016, nearly 20 years after he had left.
