After the Beatles disbanded, Harrison released the triple album All Things Must Pass, a critically acclaimed work that produced his most successful hit single, "My Sweet Lord", and introduced his signature sound as a solo artist, the slide guitar.

A prolific recording artist, he was featured as a guest guitarist on tracks by Badfinger, Ronnie Wood, and Billy Preston, and collaborated on songs and music with Dylan, Eric Clapton, Ringo Starr, and Tom Petty.

Harrison's biographer Joshua Greene wrote, "Every Sunday she tuned in to mystical sounds evoked by sitars and tablas, hoping that the exotic music would bring peace and calm to the baby in the womb.

[42][43] That moniker arose when the Beatles arrived in the United States in early 1964, and Harrison was ill with a case of Strep throat and a fever and was medically advised to limit speaking as much as possible until he performed on The Ed Sullivan Show as scheduled.

[47] By 1965's Rubber Soul, he had begun to lead the other Beatles into folk rock through his interest in the Byrds and Bob Dylan, and towards Indian classical music through his use of the sitar on "Norwegian Wood (This Bird Has Flown)".

[51] His drone-like tambura part on Lennon's "Tomorrow Never Knows" exemplified the band's ongoing exploration of non-Western instruments,[52] while the sitar- and tabla-based "Love You To" represented the Beatles' first genuine foray into Indian music.

[68] Frustrated by the cold and sterile film studio, by Lennon's creative disengagement from the Beatles, and by what he perceived as a domineering attitude from McCartney, Harrison quit the group on 10 January.

[83] Indian musicians Aashish Khan and Shivkumar Sharma performed on the album, which contains the experimental sound collage "Dream Scene", recorded several months before Lennon's "Revolution 9".

[79][94][nb 8] On its release, All Things Must Pass was received with critical acclaim;[96] Ben Gerson of Rolling Stone described it as being "of classic Spectorian proportions, Wagnerian, Brucknerian, the music of mountain tops and vast horizons".

[97] Author and musicologist Ian Inglis considers the lyrics of the album's title track "a recognition of the impermanence of human existence ... a simple and poignant conclusion" to Harrison's former band.

[115] The shows included guest spots by his band members Billy Preston and Tom Scott, and traditional and contemporary Indian music performed by "Ravi Shankar, Family and Friends".

[123] Rolling Stone called it "the chronicle of a performer out of his element, working to a deadline, enfeebling his overtaxed talents by a rush to deliver a new 'LP product', rehearse a band, and assemble a cross-country tour, all within three weeks".

[132][nb 11] The surreal humour of "Crackerbox Palace" reflected Harrison's association with Monty Python's Eric Idle, who directed a comical music video for the song.

[135] With an emphasis on melody and musicianship, and a more subtle subject matter than the pious message of his earlier works, Thirty Three & 1/3 earned Harrison his most favourable critical notices in the US since All Things Must Pass.

[142] Leng described George Harrison as "melodic and lush ... peaceful ... the work of a man who had lived the rock and roll dream twice over and was now embracing domestic as well as spiritual bliss".

[209][210] He died in the company of Olivia, Dhani, Shankar and the latter's wife Sukanya and daughter Anoushka, and Hare Krishna devotees Shyamasundar Das and Mukunda Goswami, who chanted verses from the Bhagavad Gita.

"[218] A media-only single, "Stuck Inside a Cloud", which Leng describes as "a uniquely candid reaction to illness and mortality", achieved number 27 on Billboard's Adult Contemporary chart.

[242] After Delaney Bramlett inspired him to learn slide guitar, Harrison began to incorporate it into his solo work, which allowed him to mimic many traditional Indian instruments, including the sarangi and the dilruba.

"[244] A Hawaiian influence is notable in much of Harrison's music, ranging from his slide guitar work on Gone Troppo (1982) to his televised performance of the Cab Calloway standard "Between the Devil and the Deep Blue Sea" on ukulele in 1992.

[250] During the Beatles' American tour in August 1965, Harrison's friend David Crosby of the Byrds introduced him to Indian classical music and the work of sitar maestro Ravi Shankar.

[260][261] Harrison studied the instrument until 1968, when, following a discussion with Shankar about the need to find his "roots", an encounter with Clapton and Jimi Hendrix at a hotel in New York convinced him to return to guitar playing.

[269] Harrison wrote the chord progression of "Don't Bother Me" almost exclusively in the Dorian mode, demonstrating an interest in exotic tones that eventually culminated in his embrace of Indian music.

[279] Harrison co-wrote songs and music with Dylan, Clapton, Preston, Doris Troy, David Bromberg, Gary Wright, Wood, Jeff Lynne and Tom Petty, among others.

[280] Harrison's music projects during the final years of the Beatles included producing Apple Records artists Doris Troy, Jackie Lomax and Billy Preston.

[296] His contributions to Starr's solo career continued with "Wrack My Brain", a 1981 US top 40 hit written and produced by Harrison,[297] and guitar overdubs to two tracks on Vertical Man (1998).

[299] In 2001, he performed as a guest musician on Jeff Lynne and Electric Light Orchestra's comeback album Zoom, and on the song "Love Letters" for Bill Wyman's Rhythm Kings.

[341] Around $13.5 million was generated through the album and film releases,[342] although most of the funds were frozen in an Internal Revenue Service audit for ten years, due to Klein's failure to register the event as a UNICEF benefit beforehand.

[351] Harrison recorded a benefit single, "Nobody's Child", with the Traveling Wilburys, and assembled a fundraising album with contributions from other artists including Clapton, Starr, Elton John, Stevie Wonder, Donovan and Van Morrison.

[358] Between the end of the last Beatles tour in 1966 and the beginning of the Sgt Pepper recording sessions, he made a pilgrimage to India with his first wife, Pattie Boyd; there, he studied sitar with Ravi Shankar, met several gurus, and visited various holy places.

[363] Having also helped the Temple devotees become established in Britain, Harrison then met their leader, A.C. Bhaktivedanta Swami Prabhupada, whom he described as "my friend ... my master" and "a perfect example of everything he preached".
