The Real Folk Blues is a series of blues compilation albums released between 1965 and 1967 by Chess Records, and distributed by MCA Records. Each album in the series highlighted the music of one major Chess artist, including John Lee Hooker, Howlin' Wolf, Muddy Waters, and Sonny Boy Williamson II. The series, overseen by Marshall Chess, was a reaction to the increasing audience for the blues following the British Invasion. Companion discs, titled More Real Folk Blues, were released for many of the artists. Hooker's companion disc was not released until 1991. Beginning in 1999 the albums were re-released as single-disc compilations.
