self-taught musician, Williams usually performs with a variety of instruments connected to a Boss Loop Station RC-300 phrase looper pedal, which allow him to play a riff once on an instrument, record, and repeat it. He also uses a Gibson Echoplex Digital Pro looping unit for that effect. He often then records and loops an accompanying instrument. This allows him to play unaccompanied on stage, helping him to recreate the sound of a full band. He also uses a wide variety of effects, including an envelope filter expression pedal, wah pedal, a Line 6 tap delay, a Roland GR-55 guitar synth, a Line 6 M13 Stompbox Modeler Guitar Multi Effects Pedal, and a Talk Box. His main guitars used are a Martin HD-28 and D-35, an Alvarez/Joe Veillette MTB baritone, a Gibson Chet Atkins SST Acoustic Electric Guitar with synth pickup routed to a Roland synth processor, a Fender Precision bass, a Becker Acoustic Retro, an Avante baritone acoustic guitar, a Rick Turner baritone 12-string, a Tacoma Thunderhawk, an early 1950s tempo and a Gordon Anderson custom 8-string. In addition, Williams incorporates a variety of acoustic and electric percussion instruments into his live sets, most notably a Roland Handsonic HDP-15 drum machine and a Korg Wavedrum. He also frequently performs on piano, a theremin, a Korg Kaossilator, a Macbook, and a set of Boomwhackers percussion tubes. Other projects Williams is the host of the radio show Keller's Cellar. In 2009, Williams started the "Once a Week Freek" on his website, where every week he released a new song from his album "Odd". Upon release of every song on the album, he released the entire album in one download. Due to the success of this idea, Williams chose to keep the "Once a Week Freek" project going and released a new song/video or two each week. These tracks consisted of live performances of previously recorded songs, unreleased covers of other bands' songs, or just different renditions of his own recorded music. Williams played as a member of the Rhythm Devils with Grateful Dead drummers Bill Kreutzmann and Mickey Hart at the Gathering of the Vibes festival in 2010. Williams then appeared with the Rhythm Devils in nine July shows on their summer tour.
