Kelller Williams has been called guitar’s mad-scientist, a one-man band for the new millennium, and dozens of other clever sobriquets dreamed up by fans and music journalists trying to get a handle on his uplifting and ever-shifting style of music. Though Keller’s music has evolved since he first started playing music over twenty years ago, some things have remained constant: Keller is a prolific artist, an exceptional guitarist, and an accomplished songwriter. Now, Keller’s twelfth album release looks back at a ground-breaking and already remarkable career. Aptly titled 12, the album features one standout song from each of his previous eleven releases. Keller himself dubs this his album of “hitless greatest hits.” Added to the mix is one new, previously un-recorded song. While the Keller Williams adventure has only just begun, 12 is a fantastic celebration of a musical milestone.
