Keller Williams (also known as K-Dub and the Jam-Man) is a one-man jam band from Virginia. A self-taught, percussive and rhythmic musician, Keller plays mainly on acoustic guitars while looping other instruments so that he sounds like a band but, in fact, it's just him.

His approach has seen him hailed as guitar's mad-scientist and a master of the acoustic guitar. He's put out nine one-word title albums and says his inspiration comes from his wife, life, the road, dogs and randomness.

When pressed for a definition, Williams calls his music "solo acoustic jazzfunk reggae technograss". His latest album Dream? was released last month.
