Hot Rocks 1964–1971 is the first compilation album of Rolling Stones music released by former manager Allen Klein's ABKCO Records (who gained control of the band's Decca/London material in 1970) after the band's departure from Decca and Klein.
 Released in late 1971, it proved to be The Rolling Stones' biggest-selling release of their career and an enduring and popular retrospective.
Allen Klein (December 18, 1931 July 4, 2009) was an American businessman, music publisher, writers' representative, filmmaker and record label executive, most noted for his tough persona and aggressive, innovative negotiation tactics, many of which established higher industry standards for compensating recording artists.
 He founded ABKCO Music & Records Incorporated.
 Klein revolutionized the income potential of recording artists, who previously had been routinely victimized by onerous record company contracts.
 He first scored massive monetary and contractual windfalls for Buddy Knox and Jimmy Bowen, one-hit rockabillies of the late 1950s, then parlayed his early successes into a position managing Sam Cooke, and eventually managed the Beatles and the Rolling Stones simultaneously, along with many other artists, becoming one of the most powerful individuals in the music industry during his era.
Singles 1968–1971 is a box set compilation of singles by The Rolling Stones spanning the years 1968 to 1971.
 The latest in a series of repackages by ABKCO Records, who licence The Rolling Stones' 1963–1970 recorded works, "Singles 1968–1971" is the third of three successive volumes to commemorate their non-LP releases during this era.
The Rolling Stones Rock and Roll Circus is the fifth release of The Rolling Stones music by former manager Allen Klein's ABKCO Records (who gained control of the band's Decca/London material in 1970) after the band's departure from Decca and Klein.
 Released in 1996, "The Rolling Stones Rock and Roll Circus" is a live album that captures the taping of their ill-fated 1968 TV special, which was not broadcast until decades later.
ABKCO Music & Records, Inc. (ABKCO acronym of Allen & Betty Klein and COmpany) is an American major independent record label, music publisher, and film and video production company.
 It owns and or administers the rights to music by Sam Cooke, the Rolling Stones, the Animals, Herman's Hermits, Marianne Faithfull, Dishwalla, the Kinks as well as the Cameo Parkway label, which includes recordings by such artists as Chubby Checker, Bobby Rydell, the Orlons, the Dovells, Question Mark & the Mysterians, the Tymes and Dee Dee Sharp.
 Until 2009, ABKCO administered Philles Records and its master recordings, including hits by the Righteous Brothers, the Ronettes, the Crystals and others (via a licensing deal with EMI Music Publishing, which owned the Philles catalog since the mid-1990s).
Charlie Is My Darling, directed by Peter Whitehead and produced by the Rolling Stones' manager Andrew Loog Oldham, was the first documentary film about the Rolling Stones.
 It was intended as a screen test for the band, to see how their musical charisma would translate into film.
 The footage was shot during the band's second tour of Ireland that year, on 3 and 4 September 1965, and was finished in the spring of 1966.
 It was given its premiere at the Mannheim Film Festival in October 1966.
 But the film was never officially released, due to the legal fights between the Rolling Stones and Allen Klein and a burglary in Andrew Loog Oldham's office, which saw all prints disappear.
Sticky Fingers is the ninth British and 11th American studio album by the English rock band The Rolling Stones, released in April 1971.
 It is the band's first album of the 1970s and its first release on the band's newly formed label, Rolling Stones Records, after having been contracted since 1963 with Decca Records in the UK and London Records in the US.
 It is also Mick Taylor's first full-length appearance on a Rolling Stones album, the first Rolling Stones album not to feature any contributions from guitarist and founder Brian Jones and the first one on which singer Mick Jagger is credited with playing guitar.
Rolling Stones Records was the record label formed by the Rolling Stones members Mick Jagger, Keith Richards, Mick Taylor, Charlie Watts and Bill Wyman in 1970, after their recording contract with Decca Records expired.
 It was first distributed in the United States by Atlantic Records subsidiary Atco Records.
 Beginning in 1973 it signed a distribution deal with Atlantic Records.
 In 1986 Columbia Records started distributing it.
 In the UK, it was distributed by EMI.
 The label was initially headed by Marshall Chess, the son of Chess Records founder Leonard Chess.
 It was discontinued in 1992 when the band signed to Virgin Records, but the tongue-and-lips logo remains on all post-1970 Rolling Stones releases.
The Rolling Stones No. 2 is the second UK album by the Rolling Stones released in 1965 following the massive success of 1964's debut "The Rolling Stones".
 It followed its predecessor's tendency to largely feature R&B covers.
 However, it does contain three compositions from the still-developing Mick Jagger/Keith Richards songwriting team.
 On Dutch and German pressings of the album, the title is listed as "The Rolling Stones Vol.
 2" on the front cover, although the back of the album cover lists the title as "The Rolling Stones No. 2".
"Out of Time" is a song by the Rolling Stones, first released on their 1966 album "Aftermath" (UK version).
 A shorter alternative mix was released in the US in 1967 on the album "Flowers".
 A third version featuring only Mick Jagger's vocal (and the orchestration and backing vocals from Chris Farlowe's cover version plus a new female backing vocal) was released on the 1975 compilation album "Metamorphosis", which was created under the direction of former Stones manager Allen Klein and released on his ABKCO Records label.
 (Klein owned the rights to the pre-1971 Rolling Stones catalog.)
