<P0-S0> A Sideman's Journey is the first solo album by German musician and artist Klaus Voormann, released in July 2009. <P0-S1>  Voormann is best known as the creator of the cover art for The Beatles' album "Revolver" as well as for being a much-in-demand session musician during the 1970s. <P0-S2>  He played bass on a large number of well-known albums by ex-Beatles John Lennon, George Harrison and Ringo Starr − including "All Things Must Pass", "Imagine" and "The Concert for Bangladesh" − and by artists such as Harry Nilsson, Doris Troy, Lou Reed, Gary Wright, Carly Simon and Randy Newman. <P0-S3>  Before then, Voormann had been a member of the 1960s pop group Manfred Mann. <P0-S4>  "A Sideman's Journey" is notable for including performances by Paul McCartney, Ringo Starr and Yusuf Islam (Cat Stevens), among others. <SEP> <P1-S0> Footprint is the second solo album by American musician Gary Wright, released in 1971 on A&M Records. <P1-S1>  It contains "Stand for Our Rights", an anthem-like song calling for social unity that was issued as a single in advance of the album. <P1-S2>  Wright recorded the majority of "Footprint" in London with a large cast of musicians – including George Harrison, Hugh McCracken, Alan White, Klaus Voormann, Jim Gordon, Jim Keltner and Bobby Keys – many of whom, like Wright, had played on Harrison's "All Things Must Pass" triple album in 1970. <P1-S3>  Harrison's contributions included an uncredited role as producer, and serve as an example of his support for Wright during the early stages of the latter's solo career. <P1-S4>  The ballad "Love to Survive" is one of three tracks that feature an orchestral arrangement by John Barham. <SEP> <P2-S0> All Things Must Pass is a triple album by English musician George Harrison. <P2-S1>  Recorded and released in 1970, the album was Harrison's first solo work since the break-up of the Beatles in April that year, and his third solo album overall. <P2-S2>  It includes the hit singles "My Sweet Lord" and "What Is Life", as well as songs such as "Isn't It a Pity" and the title track that had been turned down for inclusion on releases by the Beatles. <P2-S3>  The album reflects the influence of Harrison's musical activities with artists such as Bob Dylan, the Band, Delaney & Bonnie and Billy Preston during 1968–70, and his growth as an artist beyond his supporting role to former bandmates John Lennon and Paul McCartney. <P2-S4>  "All Things Must Pass" introduced Harrison's signature sound, the slide guitar, and the spiritual themes that would be present throughout his subsequent solo work. <P2-S5>  The original vinyl release consisted of two LPs of songs and a third disc of informal jams, titled "Apple Jam". <P2-S6>  Several commentators interpret Barry Feinstein's album cover photo, showing Harrison surrounded by four garden gnomes, as a statement on his independence from the Beatles. <SEP> <P3-S0> "What Is Life" is a song by the English musician George Harrison, released on his 1970 triple album "All Things Must Pass". <P3-S1>  In many countries, it was issued as the second single from the album, in February 1971, becoming a top-ten hit in the United States, Canada and elsewhere, and topping singles charts in Australia and Switzerland. <P3-S2>  In the United Kingdom, "What Is Life" appeared as the B-side to "My Sweet Lord", which was the best-selling single there of 1971. <P3-S3>  Harrison's backing musicians on the song include Eric Clapton and the entire Delaney & Bonnie Friends band, with whom he had toured during the final months of the Beatles. <P3-S4>  Harrison co-produced the recording with Phil Spector, whose Wall of Sound production also employed a prominent string arrangement by John Barham and multiple acoustic rhythm guitars, played by Harrison's fellow Apple Records signings Badfinger.
