Yeah, I saw them at SOTU '05. Opeth played four songs and they were fucking amazing, and Clutch went on right after the sun went down and rocked the place. I would rather see them do their own tours but if they both got on a festival I'd probably have to go.
In the bleak life and modern times
Under grey skies and electric light
Mortal men are living gods
More real than any god ever was
