The discography of English singer-songwriter and former member of the Beatles, George Harrison consists of 12 studio albums, two live albums, four compilation albums, 35 singles, two video albums and four box sets (one of which is with Indian classical musician Ravi Shankar). Harrison's first solo releases – the Wonderwall Music film soundtrack (1968) and Electronic Sound (1969) – were almost entirely instrumental works, issued during the last two years of the Beatles' career. Following the band's break-up in April 1970, Harrison continued to produce recordings by his fellow Apple Records acts, notably former bandmate Ringo Starr. He recorded and collaborated with a wide range of artists, including Shankar, Bob Dylan, Eric Clapton and Gary Wright. Harrison's acclaimed triple album All Things Must Pass (1970) was certified six-times platinum by the Recording Industry Association of America (RIAA) in March 2001 and, as of 2011, was still the most successful album by an ex-Beatle. All Things Must Pass produced the international number 1 hit "My Sweet Lord", which was coupled as a double A-side with "Isn't It a Pity" in the majority of countries. In 1971 Harrison recorded pop music's first charity single, "Bangla Desh", and released the Concert for Bangladesh triple live album (credited to George Harrison & Friends) to raise further funds for refugees of the Bangladesh Liberation War. His 1973 album Living in the Material World and the single "Give Me Love (Give Me Peace on Earth)" repeated the US success of his 1970 solo releases by simultaneously holding the number 1 position on Billboard'''s albums and singles charts. The remainder of his 1970s studio albums, starting with Dark Horse (1974), were all certified gold by the RIAA but performed disappointingly on the UK albums chart. Following the expiration of his EMI-affiliated Apple contract, Thirty Three & 1/3 (1976) was Harrison's debut release on his Dark Horse label, distributed worldwide by Warner Bros. Records. The 1981 single "All Those Years Ago", from Somewhere in England, was written as a tribute to the recently murdered John Lennon and became Harrison's biggest chart hit since "Give Me Love". Having clashed with Warner Bros. over the content of that album, Harrison refused to participate in promotion for Gone Troppo (1982), resulting in lacklustre sales. From 1983 until 1986, Harrison released only film soundtrack singles, reflecting his involvement in movie production. Cloud Nine (1987) and its lead single "Got My Mind Set
