Otis Spann (March 21, 1930 - April 24, 1970) was an American blues musician. Born in Jackson, Mississippi, Spann became known for his distinct piano style. Playing piano since the age of eight, Spann was already working with bands in his hometown when he was just fourteen. A few years later saw Spann move to Chicago, playing solo gigs and by the early ’50s he could be found accompanying Louisiana guitarist Morris Pejoe’s band. Spann was Muddy Waters’ pianist from 1952 to 1960 and appeared on many of Muddy’s classic tracks including the well-known "Hoochie Coochie Man", before eventually forming his own band.
