When I think of a one-man band, I can't help but picture Dick Van Dyke in "Mary Poppins." As memorable a character as Bert the Chimney Sweep is, Keller Williams has got him beat. K-Dub, as he is known to many on the festival circuit, often utilizes an array of loop pedals and a plethora of finely tuned instruments to create a full, textured sound on stage all by himself. This "one-man jam band" has a quirky songwriting style that mixes elements of bluegrass, funk, electronica, jazz, rock, and reggae. Whether Williams breaks out all the toys, or sits on a stool with an acoustic, he is a treat. Don't miss it.
Keller Williams performs Thursday, September 12, 8 p.m. at the German House Theater, 315 Gregory St. $25.50-$30. upallnightpresents.com.
