This track is reminiscent of the work of Black Sabbath. As a solo form it has two sections, a straight, driving eighth-note section and then a riff-based section where the drums shift to riding the crash cymbal. Pay attention to how the solo is mapped out to hit that change. It is important for the dynamic of what you are playing as a soloist to match what the band is doing.
