a year after the Beatles' break-up, and having established himself as a solo artist with his All Things Must Pass triple album (1970), Harrison began working with Shankar, as his producer. These 1971 projects, all released on the Beatles' Apple record label, included the soundtrack to the documentary film Raga; Shankar's Joi Bangla EP, recorded to raise international awareness for the plight of refugees of the Bangladesh Liberation War; and the live album The Concert for Bangladesh, which documented the UNICEF benefit concerts that Harrison and Shankar staged in New York that August. Twenty-three years older than Harrison, Shankar described their relationship as, variously, that of father and son (with each one adopting either role); close friends and brothers; and teacher and student. Author Ian Inglis has commented on the various differences between the two musicians, in terms of age, culture and social status: "And yet, in another sense, those contrasting factors helped to prevent any personal or professional rivalries, produced spaces and separations that their music could fill, and ultimately created … a partnership that was never competitive, but perfectly complementary." While their collaborations continued only intermittently after the mid 1970s, the depth of their friendship remained, such that Harrison would credit Shankar as being "the person who has influenced my life the most". When Harrison died in November 2001, following a four-year battle with cancer, Shankar was at his bedside, along with members of Harrison's family. Musical content The 2010 box set Collaborations was one of several reissue projects celebrating Shankar's 90th birthday. It compiles three studio albums that he and Harrison worked on together between 1973 and 1996: Shankar Family & Friends (1974), Ravi Shankar's Music Festival from India (1976) and Chants of India (1997). The first two of these albums had long been out of print, and their inclusion in the box set marked the debut CD release for both titles. Disc four contains a previously unissued concert film from 1974, titled Music Festival from India – Live at the Royal Albert Hall. Harrison's role on the three studio albums was mainly confined to that of a record producer, although his name appeared prominently on the front cover of Chants of India, and the latter was marketed as a collaborative work between Shankar and Harrison. Collaborations presents the albums in reverse chronological order, with Chants of India appearing on disc one. Chants of India Shankar and
