This is one of my favorite tunes to improvise on. It is based on the classic blues melody of "Midnight Hour Blues", recorded by Leroy Carr. I recorded with Son House as "Four O'clock Blues". It is a slow blues in E that follows the melody and chords using double stops and a dialog between the bass an melody that moves away form the typical alternating bass idea. This is not a difficult arrangement to learn and offers a great musical pallet for further exploration.
