[1]  [DOC] Dark Horse is the fifth studio album by English musician George Harrison, released on Apple Records in December 1974 as the follow-up to "Living in the Material World". Although keenly anticipated on release, "Dark Horse" is associated with the controversial North American tour that Harrison staged with co-headliner Ravi Shankar in November and December that year.
