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, as well as working with guitarist Larry Coryell, 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.
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. Williams attended Camden High School. Just after graduating high school in 1960, Williams had the opportunity to play with Gene Ammons and Sonny Stitt when Nelson Boyd reached out to Charles Sr. to cover for him. Charles Sr. was also unable to make the gig, and sent Buster in his stead. After the first set on a Friday night, Ammons and Stitt asked Williams to join the band on tour, starting in Chicago, after playing through the weekend in Philadelphia. Williams toured with them for about a year, from 1960 into 1961, until the group got stranded in Kansas City and was abandoned by Ammons, who fled without paying the band. The rhythm section managed to work with Al Hibbler for one week in order to earn enough for train fare to return home. Williams made his first two recordings with the Ammons/Stitt group in August 1961, Dig Him! for Argo Records and Boss Tenors for Verve, both recorded in Chicago
Williams' move to the West Coast facilitated touring and recording with Nancy Wilson as well as The Jazz Crusaders, with whom he recorded five albums for Pacific Jazz. According to Williams, he was "the number one sub for Ray Brown" during this time, playing with Kenny Dorham, recording a date with the Harold Land/Bobby Hutcherson quintet, and ultimately working with Miles Davis for several months in 1967
In October 1968, Williams moved to New York City and continued to work steadily, playing shows with Art Blakey, Herbie Mann, and Mary Lou Williams, while recording for Atlantic, Blue Note, and Prestige with artists such as McCoy Tyner, Dexter Gordon, Roy Ayers, Stanley Turrentine, Frank Foster, Illinois Jacquet, and, once again, Gene Ammons (recently returned from a seven-year stint in Joliet). Having worked with Herbie Hancock in the Miles Davis Quintet, Williams became a fixture of Hancock's Mwandishi Sextet, recording three albums for Warner Bros., Sextant for Columbia, The Prisoner for Blue Note, and two more under Eddie Henderson's name for Capricorn. The Mwandishi Sextet explored new electronic sounds in jazz and featured Williams on both acoustic and electric bass
