During the sixties there was the British Blues boom, containing many blues bands, one of the fineat being Peter Green’s Fleetwood Mac.
In January of 1969 Fleetwood Mac were at Chess Studios, Chicago, Jamming with the likes of Willie Dixson,
S.P Leary, Honeyboy Edwards, J.T Brown and longtime Muddy Waters pianist Otist Spann. The end result being of those sessions was the classic double album “Blus Jam At Chess” The rapport between the Mac and Otis Spann was such that they recorded another whole album together….”Colossus”.

Otis Spann is his usual emotive and exciting self, feeling totally relaxed alongside his regular drummer, S.P Leary. This coupled with Peter Green’s guitar palaying, which is probably at it’s peak on these recordings, makes for a blues album of substance. “The Biggest Thing Since Colosusss” is probably on of the most underated Blues albums.
