Michael Bernard Bloomfield was an American blues guitarist and composer. Born in Chicago, he became one of the first popular music stars of the 1960s to earn his reputation almost entirely on his instrumental prowess, as he rarely sang before 1969. Respected for his guitar playing, Bloomfield knew and played with many of Chicago's blues musicians before achieving his own fame and was instrumental in popularizing blues music in the mid-1960s. In 1965, he played on Bob Dylan's Highway 61 Revisited, including the single "Like a Rolling Stone", and performed with Dylan at that year's Newport Folk Festival.

Bob Dylan is an American singer-songwriter. Often considered to be one of the greatest songwriters in history, Dylan has been a major figure in popular culture over his 60-year career. He rose to prominence in the 1960s, when his songs "Blowin' in the Wind" (1963) and "The Times They Are a-Changin'" (1964) became anthems for the civil rights and antiwar movements. Initially modeling his style on Woody Guthrie's folk songs, Robert Johnson's blues, and what he called the "architectural forms" of Hank Williams's country songs, Dylan added increasingly sophisticated lyrical techniques to the folk music of the early 1960s, infusing it "with the intellectualism of classic literature and poetry". His lyrics incorporated political, social, and philosophical influences, defying pop music conventions and appealing to the burgeoning counterculture.
