So versatile that she was able to sustain a professional career for more than thirty years, jazz pianist, composer and arranger Mary Lou Williams ran the gamut from Dixieland to swing, bop and avant-garde. This album is among her 1960s avant-garde works, with intimate piano combos and vocal jazz choruses; it includes her well-known cantata, The Black Christ of the Andes (also available remastered and reissued on SFW40816 as a CD, complete with extensive liner notes and historic photos).
