If nothing else, Keller Williams is one of the most versatile and virtuosic musicians around. This guy can play just about anything (piano, guitar, bass, theremin, synthesizer and percussion). But what makes his music more impressive is his penchant for phase looping a wide array of different instruments during his live performances, allowing him to conduct his complicated stage show all by himself and giving the term “one-man band” a whole new definition. Though his style has constantly changed and evolved over the years (Bluegrass, Jazz, Acoustic, Folk, Rock — you name it, he’s played it) Williams’ 17th studio album, Bass, explores a genre left untouched by his previous efforts — Reggae and Funk. Even with this entry into unknown musical territory, one thing has stayed the same in Williams’ ever-changing sound: his smooth vocals and sharp songwriting. So, if you’re a “Freeker by the Speaker” or just want to know what the Dave Matthews Band would sound like if they were just one, ultra talented not annoying guy, put a “Doobie in Your Pocket” and head down to the 20th Century Theatre (3021 Madison Road, Oakley) Thursday, Oct. 18 at 9 p.m. to have your mind blown by Kdub and his eclectic set. Tickets are $25 day of show or $20 in advance through ticketmaster.com. the20thcenturytheatre.com.
