"Woke up singing a dead man's song..." is the opening line from the Warren Haynes original "Heavy Load," a line of imagery that feels like the beginning of dirt. Blues. On this album, the iconic American band puts their unique musical stamp on an incredible collection of Blues covers and originals. Haynes, the leader of Gov't Mule, hails from a Southern rock tradition of scruffy virtuosity. Gov't Mule is Warren's show, and the Blues is the informing foundation, personal and universal.
