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.
These two late-'60s albums were released at the peak of Joe South's commercial success and visibility, coinciding with his hits "Games People Play" (which appears on 1968's Introspect) and "Walk a Mile in My Shoes" (which is on 1969's Don't It Make You Want to Go Home?). This Raven reissue combines both records onto one CD, with the addition of the way-cool psychedelic soul outing "Hole in Your Soul" (from the Games People Play album) as a bonus track.
