Wonderwall Music is the debut solo album by English musician George Harrison and the soundtrack to the 1968 film Wonderwall, directed by Joe Massot. Released in November 1968, it was the first solo album by a member of the Beatles, and the first album issued on the band's Apple record label. The songs are all instrumental pieces, except for occasional non-English language vocals, and mostly comprise short musical vignettes. Following his Indian-styled compositions for the Beatles since 1966, he used the film score to further promote Indian classical music by introducing rock audiences to instruments that were relatively little-known in the West – including shehnai, sarod, tar shehnai and santoor. The Indian pieces are contrasted by Western musical selections, in the psychedelic rock, experimental, country and ragtime styles. Harrison recorded the album between November 1967 and February 1968, with sessions taking place in London and Bombay. One of his collaborators on the project was classical pianist and orchestral arranger John Barham, while other contributors include Indian classical musicians Aashish Khan, Shivkumar Sharma, Shankar Ghosh and Mahapurush Misra. The Western music features contributions from Tony Ashton and his band the Remo Four, as well as guest appearances by Eric Clapton and Ringo Starr. Harrison recorded many other pieces that appeared in Wonderwall but not on the soundtrack album, and the Beatles' 1968 B-side "The Inner Light" also originated from his time in Bombay. Although the Wonderwall project marked the end of Harrison's direct involvement with Indian music as a musician and songwriter, it inspired his later collaborations with Ravi Shankar, including the 1974 Music Festival from India. The album cover consists of a painting by American artist Bob Gill in which, as in Massot's film, two contrasting worlds are separated by a wall, with only a small gap allowing visual access between them. Harrison omitted his name from the list of performing musicians, leading to an assumption that he had merely produced and arranged the music. The 2014 reissue of Wonderwall Music recognises his contributions on keyboards and guitar. The album was first remastered for CD release in 1992, for which former Apple executive Derek Taylor supplied a liner-note essay. While viewed as a curiosity by some rock music critics, Wonderwall Music is recognised for its inventiveness in fusing Western and Eastern sounds, and as being a precursor to the 1980s world music trend. The album's title inspired that of Oasis'
