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 Sphereand 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. He had his first professional gig while he was still a junior high school student, filling in for Charles, Sr., who had double booked himself one evening. Williams later spent his days practicing with Sam Dockery, who was playing in Jimmy Heath‘s band in Philadelphia on a regular double bill with Sam Reed. Charles, Sr. hosted a jam session at a club called Rip’s and gave Williams the opportunity to put his own group together for a Monday night show in 1959, and in an effort to work his way into Heath’s band, Williams hired Sam Reed. The plan worked, as two days later Reed contacted Williams about playing in his band that coming Saturday, which demonstrated Williams’ talent to Heath, who in turn hired Williams the following week.
