 This, and subsequent more clearly country-influenced albums, have been seen as creating the genre of country folk, a route pursued by a number of largely acoustic folk musicians.Other acts that followed the back-to-basics trend were the Canadian group the Band and the California-based Creedence Clearwater Revival, both of which mixed basic rock and roll with folk, country and blues, to be among the most successful and influential bands of the late 1960s.The same movement saw the beginning of the recording careers of Californian solo artists like Ry Cooder, Bonnie Raitt and Lowell George, and influenced the work of established performers such as the Rolling Stones' "Beggar's Banquet" (1968) and the Beatles' "Let It Be" (1970).
