All Things Must Pass: All Things Must Pass is a triple album by English musician George Harrison.

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.  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.  "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.  The original vinyl release consisted of two LPs of songs and a third disc of informal jams, titled "Apple Jam".  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.
