Since 1994, singer-songwriter Keller Williams has been releasing eclectic albums, showcasing his versatility as a musician. He combines reggae, bluegrass, and rock into his songs that even include a bit of beat boxing and whistling. The guy does just about everything, and his best songs (think “Freaker by the Speaker” and “Doobie in My Pocket”) adroitly mix humorous lyrics with intricate guitar work. He plans to bring his current tour to a conclusion with an “end of the world” party in Colorado in December, so you’d better catch him tonight if you subscribe to all that end-of-the-world crap.
