US pioneering folk-rock group 1964-73. Remembered for their 12-string guitar sound and the hits `Mr Tambourine Man' (a 1965 version of Bob Dylan's song) and `Eight Miles High' 1966, they moved towards country rock in the late 1960s. The Byrds formed in Los Angeles at the time of the Beatles' greatest influence, and initially comprised Roger McGuinn (1942- ), David Crosby (1941-), Gene Clark (1941-), Chris Hillman (1942-), and Michael Clarke (1944-), most of whom had a folk-music background. Before long they went free-form psychedelic, then country and western, and dissolved 1973 after many changes of line-up that left only the guitarist McGuinn of the original members.
