Originally releases in 1969, “Keep on Moving” was the fifth Elektra release by the Paul Butterfield Blues Band. During a four-year span the group’s namesake and leader was the only original member left from their first album in 1965. Morphing in a similar direction as Michael Bloomfield’s Electric Flag, this edition of the Butterfield Blues Band prominently fronted the horn section of David Sanborn on alto sax, Gene Dinwiddie on tenor, and Keith Johnson on trumpet. The band’s direction was full tilt, horn-dominated soul music, first explored on The Resurrection of Pigboy Crabshaw, which took them farther away from the highly regarded gritty blues experimentation of East-West and the duel guitar attack of Michael Bloomfield and Elvin Bishop. This album also signaled the final appearance of AACM and Art Ensemble of Chicago drummer Phillip Wilson, whose Butterfield swan song was the collaboration with Gene Dinwiddie on the hippie gospel track “Love March.”
