Pianist Otis Spann played in Muddy Waters' band from 1953 to 1970, and was instrumental in creating the electric Chicago blues sound. These 11 tracks were recorded in the mid-'60s by Down Beat magazine editor Pete Welding, and were previously released as Otis Spann's Chicago Blues on Testament Records. This reissue omits the solo Spann material from the original disc and highlights the group recordings featuring S.P. Leary, Johnny Young, James Cotton, Willie Dixon, and Muddy Waters. While not as revolutionary as the records Spann played on with Muddy in the late '50s, you can't deny this lineup of seminal Chicago bluesmen doing what they did best.
