Trombonist Edwin Williams began appearing on recording sessions in the first half of the '70s, his first name listed as Ed, Eddie, and Edward just as regularly. Stylistically, Williams has chosen just as even a mix of R&B, soul, vocal music, and big-band projects. The jazz police, astutely guarding their realm, have considered only a few of this trombonist's appearance worthy of the swinging genre label. Much of this is big-band work, including Malachi Thompson & Africa Brass, the Jazz Members Big Band, and the Bill O'Connell Big Band. Despite the artistic worthiness of these ventures, the sound of Williams' horn has attracted the most attention during the '90s recording career of R&B chanteuse Koko Taylor, whose voice blends particularly well with the trombone. Williams has also come up with original material suited perfectly for this singer, "Never Trust a Man" among the messages.
