'Blues Jam In Chicago Vols. 1 & 2' was the result of a recording session with Fleetwood Mac in early 1969 at Chess Records in Chicago, home to Muddy Waters and Howlin' Wolf, amongst others. Then a young British blues band, Peter Green, John McVie, guitarists Danny Kirwan and Jeremy Spencer and Mick Fleetwood jammed with a number of famous Chicago Blues artists from whom they drew inspiration. Since the Peter Green-led Fleetwood Mac was so directly influenced by Chicago blues, the session acts as a kind of stylistic homecoming for the band. The following Windy City Blues legends were present at this single-day session: Otis Spann, David 'Honeyboy' Edwards, Buddy Guy, Walter 'Shakey' Horton, J. T. Brown, Willie Dixon and S.P. Leary. Willie Dixon oversaw the proceedings, and can be heard during the between-song banter giving directions and chastising Walter 'Shakey' Horton for missing his cues. Originally released in two volumes, they have been combined into one powerful package. Also available on vinyl: FLEETWOOD MAC GREATEST HITS / MR. WONDERFUL / PETER GREEN'S FLEETWOOD MAC / PIOUS BIRD OF GOOD OMEN.
