Charles Anthony “Buster” Williams (born April 17, 1942) is an American jazz bassist. Williams is known for his membership in pianist Herbie Hancock‘s early 1970s group, working with guitarist Larry Coryell from the 1980s to present, working in the Thelonious Monk repertory band Sphere and as the accompanist of choice for many singers, including Nancy Wilson.

Williams’ father, Charles Anthony Williams Sr., was a musician who played bass, drums, and piano, and had band rehearsals in the family home in Camden, New Jersey, exposing Williams to jazz at an early age. Williams was particularly inspired to focus on bass after hearing his father’s record of Star Dust, performed by Oscar Pettiford, and started playing in his early teens.
