The Incredible String Band were a British psychedelic folk band formed by Clive Palmer, Robin Williamson and Mike Heron in Edinburgh in 1966. The band built a considerable following, especially in the British counterculture, notably with their albums The 5000 Spirits or the Layers of the Onion (1967), The Hangman's Beautiful Daughter (1968), and Wee Tam and the Big Huge (1968). They became pioneers in psychedelic folk and, through integrating a wide variety of traditional music forms and instruments, in the development of world music.

Newport Folk Festival is an annual American folk-oriented music festival in Newport, Rhode Island, which began in 1959 as a counterpart to the Newport Jazz Festival. The festival was founded by music promoter and Jazz Festival founder George Wein, music manager Albert Grossman, and folk singers Pete Seeger, Theodore Bikel, and Oscar Brand. It was one of the first modern music festivals in America, and remains a focal point in the expanding genre of folk music. The festival was held in Newport annually from 1959 to 1969, except in 1961 and 1962, first at Freebody Park and then at Festival Field. In 1985, Wein revived the festival in Newport, where it has been held at Fort Adams State Park ever since.
