Keller Williams is a jam-band phenomena, known for using wild effects to make his one-man sound come off as imposing and grandiose. However, on Raw, he drops all of that for a solo, acoustic record that truly shows off his musical talent. In his sets with String Cheese Incident, Yonder Mountain String Band, and Umphrey's, you can see a wide variety of music styles manifest themselves in different forms. Raw is aptly named because that is what the record is. Most of the record is really good.
